Martin Gansberg Thirty-Eight Who Saw Murder and Didn’t Call the Police Essay

The article by Martin Gansberg, Thirty-eight who saw murder and didn’t call the police, is about an isolated event. I don’t think something like this happens a lot. Normally people would call the police or do something to help the victim. But unfortunately sometimes people can be very cold or even cruel, like in this case. Some people just don’t care about what is going on around them, if someone is in need of help or some cooperation. It’s more typical for those who live in big cities because in a busy urban life, in the crowd current they don’t have a time to stop and analyze what would be the right thing to do and they just don’t want to get involved and put themselves in troubles. In small towns people are more responsive, and the situation like this would less likely to happen. Another thing that is influent is crime and violence scenes that people constantly see on television, internet, movies. People getting used to seeing that on tv all the time in real life perceive it like another show and just watch without any action and some of them even get excited about how it’s all going to end. Luckily I have never been in situation when I had to report a crime in progress, but I know if something happens I am not going to stand there and watch. And hopefully I will never get in situation when I’m the one who needs help and no one helps. The opening line of the Martin Gansberg’s article â€Å"Thirty-eight who saw murder and didn’t call the police† states: â€Å" For more than half an hour 38 respectable, law-abiding citizens in Queens watched a killer stalk and stab a woman in three separate attacks in Kew Gardens. † But it doesn’t mean that they were staying around like in arena watching the killer slaughtering a victim from the very beginning to the end. The author uses little exaggeration to dramatize what happened. It may not be the fact but it expresses author’s position. It shows how angry and disappointed he is, it shows his condemnation. Although writers, especially reporters, have an ethical responsibility to be accurate, little exaggeration and distortion can take a place, what can help author to express their position and their point of view. What matters is what exactly and how much has been distorted. For example, article says that the killer made three attempts to kill the woman. If indeed the victim died from the first attempt and the killer run away after that, but author changed the story to make it more dramatic, that would be very serious distortion of the story.

SWOT Analysis of Nokia

Introduction Nokia was founded in 1865, is headquartered in Finland, mainly engaged in the production of mobile communication products multinational, is the world's third largest mobile phone manufacturer. February 2011, Nokia and Microsoft entered into a strategic alliance and the depth of cooperation.Over the past few years, Nokia shares have gradually from London, Frankfurt, Paris and Stockholm stock market delisting. February 9, 2012, due to poor management, Nokia announced layoffs in three mobile phone manufacturing plant 4000. April 11, 2012, due to huge losses for several quarters, Nokia shares plunged 17 percent, the market value has shrunk $ 5 billion a day, to fall back to 1997 levels. In the September 3, 2013 Microsoft officially announced a $ 3.79 billion euros acquisition of Nokia mobile phone business, to 1.65 billion euros while the acquisition of its patent portfolio, which means that Microsoft's acquisition of Nokia's business and assets of the expenses totaled 5.44 billion euros (about $ 7.17 billion).Nokia failed because of its long-term monopoly in the mobile phone market, resulting in a slack, underestimate the enemy emotions; enterprise bureaucracy has become popular, gradually lost self, lost the incentive to innovate. And in the mobile phone industry has changed, especially after the popularity of 3G mobile Internet revolution brought, Nokia has not been able to face changing market to make the right judgments.Political factorsLegal constraints, such as 3G, must be considered because many businesses plan to make a profit so they may be tempted to misinform their customers about pricing, products’ quality and the availability of their goods. Also, they may try to cut expenses by using lower quality materials in their products, such as weaker resources for Nokia cases and batteries. Also some companies may set out their waste in ways that harm the environment without ensuring high standards of hygiene and safety in the workplace.Inc luding, outlet stores, which are illegal and can cause legal problems for companies. In 2000, the UK Government started to accept bids from thirteen companies who wanted to run a licence to sell next-generation mobile phones. It raised  £22.47, a neat sum to anybody. However, the companies began to refuse paying the huge amount of money for the licences. The UK auction was structured so that each challenger bid was planned to be a certain percentage higher than  the previous bid. This unexpectedly resulted in the size of bids strengthening sky high at a rate of over 150 rounds of bidding.Economic factors Current economic indications, such as exchange, inflation rates, unemployment, gross national product can orient companies how to determine their policies. The other significant factor is the global economic situation for an international company such as Nokia. Considering the last two years of global handset devise market, there is a downturn in the sales.The global economic re cession and the related domestic economic crises are the most significant factors of shrink mobile phone industry. So its natural result is decrease of Nokia's mobile phone sales. According to a resource firm, named Gartner, worldwide mobile phone sales decreased 8.6 % in the first quarter of 2009 compared with first quarter of 2008. Nokia's market share dropped to 36.2 per cent to 39.1 per cent in the last quarter of 2008 (Gartner, 2009).Technological factors Nokia is not a company without a sense of crisis .Instead, Nokia has long recognized the existence of the crisis . IPhone, launched in 2007, Nokia was first proposed in the global transformation of the Internet strategy. Of all the mobile phone manufacturers , Nokia is the first high profile vendors need restructuring .At the time, Nokia's transformation direction can be attributed to Ovi – this has now been forgotten by many names. Concept Ovi by Nokia on August 29, 2007 and the company also announced a comprehensive r estructuring strategy .In response to industry changes , the Nokia Ovi store via software programs , music , maps , mail, and N-Gage mobile gaming platform , five major business transformation to fully support the Nokia Mobile Internet .In order to conform to Internet trends , Nokia also the first to make a lot of † free † move. For example in January 2010 , Nokia announced that its worldwide smart phone walking and driving navigation will all free. You know, a well-known high German navigation, Baidu navigation , etc., until the end of last month , was determined to totally free.But Nokia seek self- transformation and the result is a failure. Some call it summed up the lack of mobile Internet genes, some say lack of execution , also said that Nokia's big company disease dragged its own transformation . Anyway, Nokia does not rely on their own efforts to turn things around .IBM not so computerDecember 8, 2004, Lenovo Group in Beijing announced $ 650 million in cash and s tock worth $ 600 million (total value of about 10 billion yuan) won including Think brands, including IBM PC business (PC Division). Completed, IBM Lenovo Group holds 18.5% of shares, while Lenovo Group Lenovo Holdings will occupy about 45% of the shares. According to the agreement, Lenovo also within five years, IBM's brand. If successfully completed the acquisition of Lenovo, Lenovo will then become the world's second only to Dell, Hewlett-Packard after the third-largest PC vendor.Lenovo's acquisition of IBM's personal computer business before, its revenue was 30 billion U.S. dollars, after the merger is completed, the business volume reached $ 13 billion, so the company's foreign operations accounted for more than 75% of all business proportion, legal risk has changed greatly . Another example was a very well-known Chinese enterprises in mergers and acquisitions, foreign workers paid after termination of the contract is almost equivalent to the original acquisition cost of all th e funds.ConclusionChange management generally is difficult but no undoable. With a world closing in every day. not only international blue-chip companies are forced to critically reassess and. if necessary, change their business model, but also their organizational structure or their corporate culture. Most failed change projects underestimated or simply did not take into account the human factor.To avoid this failure the assistance of change experts or change agents (in most cases professional consultants) should be sought. Not only that most employees have no or little experience in the field of change management. In most cases people are used to their environment and emotionally unwilling to change.

The process of leadership is not homogenous in all contexts i.e Essay - 2

The process of leadership is not homogenous in all contexts i.e. industry, country - Essay Example The process of leadership is not homogenous in all contexts i.e. industry, country As the world’s largest beverage market, the size of the U.S carbonated soft drink industry stood at more than $60 billion towards the departure of the twentieth century.The key issue with regards to the American beverage industry is that of the unparalleled level of concentration which is enjoyed by PepsiCo and the Coca-Cola Company within the market. Liu (2012, p. 119) understands that the fundamental characteristics of the carbonate soft drink industry necessitate that competitors should have the capital to launch extensive marketing campaigns, maintain cost-efficiency and invest in technological advancement to successfully compete in the industry. However, the presence of these elements can be categorized as a barrier to entry in the industry as smaller companies do not have the means to approve massive investments. This observation can be identified as one of the key reasons behind the dominance of companies such as PepsiCo and the Coca-Cola Company within the U.S beverage industry. The aspect of competition with regards to the beverage industry is closely linked with the dynamics of the external or macro environment in which the firms operates however, several other features of this environment have the capability to influence organizational activities and managerial decision making. . For example, the harmful effects of carbonated soft drink consumption have often come into question by researchers for promoting health related issues and obesity. In addition to this observation, the U.S beverage industry has also addressed several scandals that have emerged from the very beginning. From the accusation regarding the presence of aborted fetus cells as an ingredient of Pepsi to the alleged presence of chlorine content in Coca-Cola, the multi-billion dollar beverage industry in the United States is marked by a plethora of issues, accusations and critics of the product that it promotes and sells to consumers belonging to every age-group. However, the foc us of these issues is towards addressing the needs of the modern, health-oriented and aware consumers who demand products that can minimize health risks and promote their well-being. Given the dynamics of the U.S beverage industry, it is most appropriate to examine the notion of leadership as an ongoing and comprehensive process. According to Northouse (2010, p. 5); â€Å"The process viewpoint suggests that leadership is a phenomenon that resides in the context of the interactions between leaders and followers and makes leadership available to everyone†. In the present scenario, the foremost challenge of the U.S beverage industry is that of innovation, which in a broader sense is not linked with new product development but the formulation of effective strategies and frameworks that can allow leaders to respond to â€Å"†¦the demand of competitive pressure to fast-changing consumer needs and trends†¦Ã¢â‚¬  (Isaken and Tidd 2006, p. 265). As stated previously, the b usiness model on which the beverage industry is based on a concept that does not support the presence of small companies who cannot invest in the development of brands in addition with the launch of marketing campaigns to attract a large customer base. Therefore, the beverage industry in the United States is dominated by two key players who engage in fierce competition to deter the absolute dominance of the other. In order to cope with the scale of the industry’s operations and the issues that it faces, the process of leadership is marked by the

Time Magazine Research Paper Example | Topics and Well Written Essays - 1000 words

Time Magazine - Research Paper Example Hadden co-founded Time Magazine after they worked together on the Yale Daily News in Yale but the death of Britton Hadden in 1929 saw Luce’s name becoming the most dominant name in 20th century American as the Time Magazine grew to be one of the most successful magazines in American history. The first Time Magazine publication came out on March 3, 1923 as Vol. 1 Number 1. The difference between the first Time Magazine publication and what has been the distinguishing feature of Time Magazine was the lack of the classic red border. The cover of the first Time Magazine publication featured John G. Cannon, an 86 year old retiring member of congress who had served 23 times in the House of Representatives. The main reason given for the cover having Cannon was that it represented the main aim of Time Magazine of speaking to the readers through people. The aim of the founders was to create a magazine that informs busy readers in United States and the rest of the world on current events in a systematic, organized, and concise manner. After its incorporation in 1922 by Henry Luce and Briton Hadden and the first publication in 1923, Luce purchased Life Magazine in 1936 and made it a photojournalism publication. The company began trading in the New York stock exchange in 1964. At the passing of Luce in 1967, Time Magazine was worth $ 109 million dollars and the development and growth of Time Magazine continued. In 1972, Time and Chuck Dolan launched Home Box Office (HBO) that has grown over the years to rack in almost $5 billion in revenue and 100 million subscribers. In 1989, Time merged with Warner Communications forming a company with $ 10 billion annual revenue and valued at $ 15 billion dollars. 1995 saw the purchasing of Turner Broadcasting system by Time but in 2000 Time merged with AOL in the biggest merger and acquisition deal ever. Time magazine had a disastrous association with AOL that led to an investigation into its accounts leading to the ditching of AOL

Salem Witch Trials Essay Example | Topics and Well Written Essays - 1250 words

Salem Witch Trials - Essay Example The fear that swept through the colony would in today's time be irrational but during this era of Puritanism it was a balanced and bona fide response. Puritans believed that the devil offered material recompense for collusion with him. Some of the evidence used in the trials was spectral evidence whereby those who had been affected claimed they had seen the apparition of the person who had afflicted them. In order for this to happen the Devil, it was said, had to be given permission by the accused to use their shape when appearing before their victims. A minister who was involved in the trials, Increase Mather and other ministers wrote a letter to the courts of Salem insisting that spectral evidence alone should not be used to convict the accused. (Mather, 1693) During one trial the accused Mary Osgood in her defense stated "the Lord would not suffer it so to be, that the devil should afflict in an innocent persons shape". She talked about how the devil had offered her rewards for her collusion and whilst she had agreed was able to prove that actually her life had become worse since her involvement with Satan and therefore had never fulfilled any commitment made to him (Reis, 1997). Consequently her life was spared. It was the women who denied conspiracy with Satan that faced execution for witch craft and testified that they would gain absolution from God upon death due to their innocence. At Sarah Goods execution she proclaimed the following to the minister "I am no more a witch than you are a wizard and if you take away my life God will give you blood to drink" (Reis, 1997). During the trials the situation reached hysterical proportions and it is the sheer size of the occurrences of accusations that has warranted further investigation to create a rationale for the multitude of persecutions. Even during the trials the hysteria generated called some individuals to instigate an examination of possible alternatives to witchcraft. The initial accusations in Salem Village resulted with the testimony of Betty Parris, age 9, the daughter of Reverend Samuel Parris, the Puritan Minister of Salem during the trials, and her cousin Abigail Williams, age 11, the young girls began having fits that were said to be "beyond the power of epileptic fits or natural disease to effect" (Hale, 1697). Other women in the village also began to display similar symptoms shortly after. The women accused of affecting the girls through the powers of witchcraft were Sarah Osborne, Sarah Good and a female slave called Tituba who was indentured to the Parris family. Sarah Osborn was marri ed to one of her own servants and rarely attended church, Sarah Good was renowned for begging and asking for shelter and Tituba had a different background to that of Puritanism. The girls had accused Tituba of witchcraft and she was consequently beaten into a confession that she was indeed a witch. Due to these three individuals hardly measuring up to being what would have been deemed at the time as respectable members of the Puritan community they were obvious suspects for the rituals of witchcraft. However it wasn't long before upstanding and often influential members of their community began being accused

Womens Inclusion in Education Essay Example | Topics and Well Written Essays - 1250 words

Womens Inclusion in Education - Essay Example In many countries, cost of education has been rapidly growing and this substantial and constant rise has discouraged many families to provide quality education to their all children. Consequently, this has led to believe that education can only be given to male children rather than to female children. Additionally, in some countries, religious beliefs also discourage the followers to provide education to their girls. For example, in the religion of Islam, some scholars believe that girls should not be allowed to receive an education. And in order to support their perspective, they contend that allowing girls for receiving education would provide them an opportunity to freely interact with boys which become a major cause of social evil in their society. However, this type of belief has made this world more insecure and unsafe as well. For example, because of this backward thinking and perspective, the world is facing the menace of terrorism and extremism; and the events of 9/11 are th e result of one of such insane manifestations. As a result, it can be extracted that because of this thinking, many innocent people lost their lives in that attack. At the same time, the followers of that thinking are still causing harm to humans and humanity as terror attacks are still taking place in a number of other countries as well. In order to avoid this cost, which is being paid by the whole humanity, it has become highly necessary and unavoidable to work against this belief and promote and encourage woman education.

Global warming Thesis Example | Topics and Well Written Essays - 1750 words

Global warming - Thesis Example The major controversies surrounding global warming, include - skepticism regarding the change in climate beyond natural variations; questionable evidences against the factors responsible for global warming as well as the likely scope and extent of its impact; effectiveness and validity of the strategies suggested to combat global warming and for reducing carbon footprints; and the estimated size, effect and consequences of the phenomenon. Skeptics have raised serious concerns and questions regarding the scientific consensus about the effects of global warming as well as the adequacy of facts and evidence supporting the theories of global warming. The debates and cynicism regarding the far reaching effects of global warming are large observed among the policy makers and political spheres, rather than within the scientific communities. Furthermore, doubts have also been raised regarding the causes of global warming. According to some the main cause of global warming is yet to be explor ed while others consider it as a natural phenomenon while yet others consider human activities, responsible for the phenomenon. There are various arguments put forward by skeptics, and the same have been rebutted with facts and evidences in the following section, thus further substantiating and reaffirming the fact that global warming is indeed real and not a myth, contrary to rising opinion. Criticisms and Rebuttals: 1. The earth is not warming, instead, it has cooled down over the past decade: According to the skeptics, the earth is not warming, as claimed by the scientists and even if it is, the extent of damage as predicted by them is over exaggerated. They further claim that there exists data / scientific evidence which suggest that the earth is in fact, cooling, rather than warming. It is further stated that the planet was warming during the 20th century but the warming had stopped over a decade ago, and the Earth has been cooling ever since 1998 (Singer & Avery, 2007). This i s supported by the fact that the periods between December 2007 and November 2008 have been the coldest periods of the decade (Singer & Avery, 2007). It is argued that although the earth may not be cooling, but the evidence claiming that the earth is warming, is not credible and holds no relevance. Rebuttal: Although the evidence showing that the average temperature has fallen during the decade holds relevance, but the same, does not prove that the earth is cooling. The differences in temperatures is mostly because of the factors used for comparison, for instance, the year 1998 which was used as a base, was the hottest year of the century. Contrary to the claims made by the skeptics regarding â€Å"cooling of the Earth† the planet never stopped warming. The temperatures during the year 1997 were hotter as compared to that in the year 1995, while 1998 soon surpassed 1997 to become the hottest year of the decade, which in turn was replaced by years 2002 and 2003. According to NA SA, the year 2007 was the hottest year of the century on record. All these reports clearly show that the temperature is constantly rising, with no signs of slowing down (Casper, 2009; Robinson, 2007; Singer & Avery, 2007). 2. Statistics related to surface temperatures are unreliable and are blown out of proportion. The crisis

Astroturf campaigns in politics Research Paper Example | Topics and Well Written Essays - 250 words

Astroturf campaigns in politics - Research Paper Example An Astroturf campaign looks like a real political campaign, but few-placed interest units orchestrate such events for given selfish reasons. In this case, gaining grassroots support is a legitimizing force that ensures a given campaign seems like a real campaign. There are several consequences of such campaigns. To begin with, Astroturf campaigns increase the likelihood of passing the wrong policies. A country operates through policies that define how government entities make decisions. In every sector, there are policies that guide the operations and management of resources. Wrong policies, therefore, may direct a country towards a crisis, especially, for sensitive sectors such as health.In addition, these campaigns may lead to the exploitation of the public. This occurs in case of election of incompetent officials. Selfish political interests may influence the organization of such campaigns. This occurs because such interests may vouch for a politician who forms policies that favor given ends (Perrucci and Wysong 66). In turn, the rest of the population bears the catastrophe of wrong policies. This is usually evident in the case of competition laws that may disfavor small and upcoming firms. Astroturf campaigns destroy the morality of politics, as voters do not attain the chance of voicing their objective opinions. Such campaigns may be so sensational and delusional such that decided voters sway towards fads. It is essential for politics to create an environment whereby each opinion reflects in the ballot.

How should the state of Colorado generate funds for Higher Education Essay

How should the state of Colorado generate funds for Higher Education - Essay Example The state of the education system in the state is regarded as one of the most productive in the nation. In addition to that, it is a leader in the development of green technologies. The state promotes research initiatives and it is a major contributor to research in different areas. According to a report, the economic consequences of research institutions in the state are incredible. The recent reports show for the University of Colorado and Colorado State University show that each$1 of state general fund produces $13.2 of additional economic activity, therefore, it is imperative for the government to increase the general fund for Colorado for the interest of the country.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The reasons for the scarcity of funds in the State of Colorado despite its economic significance are several folds. An analysis of the root cause of the problem can provide us valuable suggestions for how to bridge the gap between the supply and demand of funds. Firstly, the higher education crisis is triggered due to the fact that Colorado’s system has failed to meet the demand created by demographic shifts. The most growing ethnic minority, Latinos, are underrepresented in the higher education system. In addition to that, the state imports a significant proportion of the population with postsecondary education while failing to accommodate the needs of its current citizens. The institutions in Colorado significantly differ in enrollment of low-income students as compared to the income level of the counties they serve. Finally, the state ranks at the lowest on the basis of state funding per FTE.

Vinegar as a Rust Remover | Experiment

Vinegar as a Rust Remover | Experiment Abstract Despite the vast research regarding rusting, still many people do not recognize the harmful effect it can to environment and to take precaution measure to avoid or prevent rusting. Results of study show U.S. had to spend total $276 billion, approximately 3.1% of the nations Gross Domestic Product (GDP) for corrosion direct cost. Therefore, these study is to find optional of artificial way to remove rusting from any other metal. For my research, I choose vinegar as a substance that has the potential to remove the rust stain from metal due to presence of acid in its content. Vinegar is easy to be obtained and usually use as households. I choose three different types of vinegar brands and analyzed its percentage by mass of acetic acid using acid-base titration technique. Then, I test the strength of each vinegar on rate of removing rust on rusted iron nail by removing the rust form. After that, I compare which vinegar has the highest rate of removing rust compared to its percentage by mass of acetic acid. As the result, I found out that different type of vinegar has different percentage by mass of acetic acid. But my experiment shows that, the higher percentage of acetic mass in the vinegar content, does not always lead to high rate of rust stain removal. These maybe due to my limitation of the research because I assumed that only acetic acid in vinegar reacts with the iron(III) oxide. Still, my research able to prove that vinegar can act as a potential rust stain remover but in low degree because acetic acid is weak acid. My research could help and provide people an easy way to remove rust from their accessories as vinegar could be easily obtained. 1. Introduction Vinegar can be define as a sour liquid obtained by result through acetic fermentation of dilute alcoholic liquids and used as a condiment or preservative. Aside from utilized widely, vinegar also can accommodate more than one purpose which usually used to enhance food taste. Vinegar is made through two stage of biological processes. These distinct process resulted from the action of innocuous microorganisms. In these process, yeast and Acetobacter is used to convert sugars (carbohydrates) into acetic acid. The first stage of process is called alcoholic fermentation. It occurs when yeasts convert natural sugars to alcohol under controlled conditions. In the second stage of process, Acetobacter which is a group of bacteria, changes the alcohol resulted from alcoholic fermentation to acid. This is the acid fermentation that forms vinegar. Since vinegar can be made from anything with sugar, there are probably too many variants to count made in countries throughout the world.[1](Kellen, 2 005, Vinegar Institute Site) Rust is define as the red or orange coating that forms on the surface of iron when exposed to air and moisture surroundings, consisting mass of ferric hydroxide. These ferric oxide is formed through oxidation. Rust forms due to the reaction of oxygen dissolved in dihydrogen monoxide(water) with iron. Rust also can be known or called as corrosion of metal.[2] (Holleman, Wiberg, 2001 Inorganic Chemistry Academic Press: San Diego) Rust is a general term to describe several different oxides that formed when an iron undergo corrosion. Some of the oxides are Fe(OH)2, Fe(OH)3, FeO(OH), and Fe2O3.H2O. The prevalent rust that can be found is a reddish-brown, Fe2O3.H2O. The oxygen in the air dissolve in water and promote the rust to start to compose. The rust also can be determine as an electrochemical process. The process of exchange of electrons (electricity) is conducted by chemical reactions in part of the electrical circuit. The surface of metal that exposed to electrolyte will undergo series of chemical reactions. Oxidation reactions (corrosion) occur at the surface of the anode while reduction reactions occur at the surface of the cathode.[3] (Jones, Denny (1996)  Principles and Prevention of Corrosion.) By observation, we could descried that rust occurs very easily because the presence of air and water or wet condition virtually presence anywhere. We could see around ourselves rusting is occur greatly. Rust changes steel into a different material, one that is impuissant or weaker than the original steel. Rusting is a immensely colossal problembecause so many things people use every day are made out of steel, like cars, bicycles, trucks, bridges, roofs, holding tanks, machinery, nuts, and bolts. When these objects are unprotected and exposed to water, they rust, and this damage can costs a lot of money. Rust also dangerous to human because a rusting iron nail can cause health issue such as tetanus if the iron nail pierce to human skin. Yet steel perpetuates to be widely used because it has an excellent strength-to-weight ratio. Also known as the best of all the common building materials. In addition, it is non-flammable, resistant to mold and termites, does not expand or contract und er temperature changes, and can be made with a consistent quality.[4] (Miller, L. (2003, July 31).  Corrosion). Therefore, we must take alert and precaution about rusting of these iron metal. The topic that be investigated in this extended essay is about rusting or corrosion and the way to prevent rust. Thus, my research question is to analyse the percentage by mass of acetic acid in different type of vinegar brands by using titration method and to investigate the potential of vinegar as rust stain remover. Therefore, my extended essay required two experimental procedures. My hypothesis for first experiment is that different types of vinegars have different percentage by mass of acetic acid. If the result of experiment one parallel with my hypothesis, second experiment could be carried out which is to investigate the potential of vinegar as rust stain remover. My hypothesis for second experiment is that the higher the percentage by mass of acetic acid in vinegar, the more efficient the vinegar to act as rust stain remover. The significant of my research is to investigate a cheapest and easiest way to remove rust. In this research, I choose vinegar as the potential method to remove stain rust because vinegar contain acetic acid . Vinegar could be easily found and present almost in every living house. Because acid is corrosive, it occur to me that the acid could corrode the rust stain from metal. To test the validity of my statement, a research and experimental procedure is carried out to justify the validity of my research question. The chosen area of study is rusting since my experiment focus more on rusting. These experiments included several methods such as acid base titration. Vinegar is acidic. Therefore, it will be titrated with base solutions, sodium hydroxide. The titration method is carried out to find the volume of base needed to neutralize the acid solution of vinegar. These method is essential for the experiment to find the percentage by mass of acetic acid in vinegar. Second method is rusting of iron nail. I could not choose any random iron nail to conduct my experiment because the result will not be accurate and precise as they could have different degree of rusting. Therefore, I buy iron nails that not rusted yet and undergo experimental procedure for the iron nails to rust under constant condition. These method needed to carry out so that the iron nails undergo rusting in constant activity. Then, the iron nails could be tested with the vinegar. In my experiment, I used some instrument from the chemistry laboratory. The instruments I used is pH meter. The pH meter is used to find the pH of different type of vinegar. I also use burette which is necessary for the titration method. The burette is used to find the volume of base needed to neutralise the acidic solution. I also used electronic balance to weigh the iron nails initial mass before in undergo rusting and the final mass after the iron nails undergo rusting. Stopwatch is used to record the time taken for the acid to remove the rust stain. *Due to some error, all the pictures for the experiment have loss. 2.

Table 2 : Variables for experiment to determine the time taken for the vinegars to remove rust 2.2 Methodology for neutralisation process To find the percentage by of acetic acid in different types of vinegar brands, a neutralisation process follow the standard procedure is carries out. First , the apparatus is set up . The burette is clamped on the retort stand. Then, 2.0 ml of vinegar is measured using measuring cylinder. An empty conical flask is weighed. Then 2.0 ml vinegar which is Earth Brand is poured in the conical flask. The conical flask is weighed again. This procedure has to be carried out to find the mass of 2.0 ml of vinegar assumed that different vinegars has different density. After that, 48.0 ml of distilled water is measured using measuring cylinder. Then, the distilled water is mixed with the vinegar in the conical flask. This procedure has to be carried out because vinegar is very concentrated so dilution process has to be done. The pH mater is used to find the pH value of vinegars. After mixed, the initial weight of vinegar with conical flask is measured using weighing balance. Then , sodium hydroxide is filled in the burette. The conical flask is placed under the burette. 3 drops of phenolphthalein is added into the diluted vinegar. The neutralisation process is started as soon the alkali is added into the conical flask. The sodium hydroxide is assumed to only react with the acetic acid presence in the vinegar. The conical flask is swirled gently. The initial colour for the acidic solution is colourless. As the acid solution undergo titration, the colour change from colourless to pale pink colour. The end of titration is indicated when the mixture remains in pale pink colour. The titration process is stopped. The volume of sodium hydroxide needed to neutralise 2.0 ml of vinegar is recorded and final weight of vinegar with conical flask is weighed. The experiment above is repeated twice to get the average reading of volume of sodium hydroxide needed to neutralise the acid solution. All the data is recorded in the table. The experiment procedure above is then repeated using different type of vinegar which is Yeos and Jalen. Burette,  ±0.05 cm3 Different vinegar brands (Jalen, Yeos, Earth Brand) Beaker,  ±0.5 Conical flask , ±0.5 Retort stand and clamp Pipette and ph meter Phenolphathalein Weighing balance ,  ±0.0001 Sodium hydroxide (1.0 molar) Rod and distilled water 2.3 Methodology for rusting process and rust stain removal This experimental procedure is carried out because it is hard to determine the degree of rusting of any random metal. Therefore, I fixed the type of metal use which is iron nails and the time left for iron to rust which is approximately 7 day (1 week) . The materials is ready and apparatus needed is set up. The initial mass of each iron nail is weighed and the data is recorded. The 5 iron nails is marked such as iron nail A, iron nail B and consecutively by using a small piece of paper attached to each nail. Then , a mineral bottle is cut to get the bottom part of mineral bottle and form a cup like. Then, the cup is filled with small amount of tap water. All iron nails is dipped in the water and left to be exposed to air in the laboratory for seven days. After seven days , all iron nails are take out from the bottle. Then, each iron nail which already rusted now is weighed again to get mass of rust with the iron nail. The mass of rust formed on each iron nail is found by subtracted the final weight of iron nail with its initial weigh. Then, the average mass of rust formed is calculated. All the data of the experiment is recorded in a table. The experiment above is repeated twice. The process to remove rust stain is carried out. Vinegar is inserted into a transparent cup. The rusted iron nail is immersed into the cup contained vinegar. The reaction is observed. The time taken for the iron rust to be remove completely by the vinegar from the iron nail is recorded by using stopwatch. The same procedure done to all 5 iron nails . The average time taken needed to remove the rust is calculated. The data and result is tabulated. The experiment above is repeated using different type of vinegars. Apparatus and materials Burette,  ±0.05 cm3 Beaker,  ±0.5 Bottle cup Different vinegar brands (Jalen, Yeos, Earth Brand) Conical flask , ±0.5 Measuring cylinder,  ±0.05 Weighing balance ,  ±0.0001 5 Iron nails Distilled water 3. Data collection and processing 3.1 Data collection and processing for experiment   Quantitative data Type of vinegar brand Weight of empty conical flask (g)  ±0.0001 Weight of 2.0 ml of vinegar with conical flask (g)  ±0.0001 Mass of vinegar  ±0.0002 (g) Earth Brand Qualitative data The initial colour of vinegar and sodium hydroxide is colourless. The colour of vinegar solution remains colourless even after phenolphthalein is added. When the mixture undergo titration process, the mixture remains colourless but when the end point of titration reach, the colour of mixture turns from colourless to pale pink. Equation for the neutralization process = CH3COOH (aq) + NaOH (aq) à ¢Ã¢â‚¬  Ã¢â‚¬â„¢ CH3COONa (aq) + H2O (l) Calculation of percentage by mass of acetic acid in vinegars. 1. Earth Brand Calculate number of moles for NaOH = MV 1000 (32.54 ml of NaOH solution added x 1.0 molar of NaOH) 1000 = 0.03254 moles of NaOH uncertainties =( 0.05/ 32.54) x 100% = 0.15 % CH3COOH (aq) + NaOH (aq) à ¢Ã¢â‚¬  Ã¢â‚¬â„¢ CH3COONa (aq) + H2O (l) From the equation , the acetic acid in vinegar reacts with sodium hydroxide in a 1:1 ratio. 1 mole of acetic acid reacts with 1 mole of sodium hydroxide to for 1 mole of sodium acetate and 1 mole of water. Thus, 0.03254 mole of acetic acid reacts with 0.03254 mole of sodium hydroxide to form 0.03254 mole of sodium acetate and 0.03254 mole of water. Calculate the amount of acetic acid in Earth Brand. Therefore, Molecular mass calculation: 12.0107 + 1.00794*3 + 12.0107 + 15.9994 + 15.9994 + 1.00794 = 60.05196 g/mol To find the mass of acetic acid in vinegar is given by the formula number of mole x molar mass of acetic acid Thus, 0.03254 moles x 60.05196 g/mol = 1.954 g of acetic acid  ± 0.15 % To calculate the percentage by mass of acetic acid in vinegar (Earth Brand): Mass of vinegar use= 2.2837 g uncertainties = (0.0001/2.2837) x 100% = 0.0044 % mass of acetic acid in vinegar = 1.9540 g The percentage by mass of acetic acid =(1.9540/2.2837 ) x 100 = 85.56 % uncertainties = 0.0044 + 0.15 = 0.1544 % Therefore, the percentage by mass of acetic acid in Earth Brand is = 85.56 %  ± 0.15 % The method of calculation of percentage by mass of acetic acid for other vinegars is same with the calculation above. Therefore, the result for the calculation is tabulated. Discussion The 2.0 volume for vinegar used needed to be weighed to find the mass of vinegar as I assumed the density for vinegar is different from density of water. From the result, it shows that different vinegars has different density, therefore different vinegars will have different mass of 2.00 volume used. I also assumed that during neutralisation process, the sodium hydroxide will only reacts with the acetic acid presence in the vinegar. Based on the result , it shows that different type of vinegar brands has different percentage by mass of acetic acid of vinegar of different brands. Jalen has the highest percentage by mass of acetic acid followed by Earth Brand and Yeos. These explained that why different vinegars have different ph value. Acetic acid is weak acid. The higher the percentage by mass of acetic acid, the lower the pH value of the vinegar. Hypothesis for experiment one is accepted. Different type of vinegar has different percentage of acetic acid of vinegar. Thus, experiment two can be conducted. 3.2 Data collection and processing for experiment 2 Quantitative data The iron nail pale brown in colour while the tap water and the vinegar is colourless. When the iron nail is left in the bottle cup, there is no immediate reaction occured. After several hours, a reddish brown substance start to appear around the iron nail. After several days more reddish brown substance deposited around the iron nail like coated it. When the iron is immersed in vinegar inside a cup bottle, bubble formed and the reddish brown substance fall off from the iron nail. The colour of vinegar turned slightly from colourless to pale reddish and the reddish substances settle at the bottom of the cup bottle. Later, it dissolve in the vinegar. 4. Processed result Discussion To put in a simple words, rusting is the corrosion of iron and readily occurs in the metal in the presence of water , oxygen and iron. The formation of a reddish brown substance like which appeared and adheres to the iron nail is called rust. Based on the research, it shows that vinegar could serve as one of the substance that can remove rust stain on metal due to the presence of acid. From the experiment , It clearly shows that different vinegar has different degree of removing the rust stain because due to different percentage by mass of acetic acid in the different type of vinegars. After rusting process occurs on the iron nail, the iron nail weighed more. These is because rust  forms when iron metal is oxidized by oxygen in the presence of water . Iron oxide is another term for rust. Iron oxide as a molecule and consist of three elements which is of iron with oxygen and water. From the result obtained based on the experiment, it shows that the rust form is originally mass from the iron but the mass of oxygen and water comes from the atmosphere. When the rust form on the iron nail, the mass of iron rust increased by the mass of oxygen and water that combined with the iron. Therefore, iron nail weight more after rusting process occurs due to addition of these elements from atmosphere. In the presence of oxygen and water, Reduction half equation: 4e- + 2H2O(l) + O2(g) > 4OH-(aq) The tip or the head component of iron nail is easily oxidised. The crystal lattice of iron is distorted and the iron atoms will be facilely oxidised. Oxidation half equation: 2Fe(s) > 2Fe2+(aq) + 4e- Therefore the overall net equation for the chemical reaction is 2Fe(s) + 2H2O(l) + O2(g) > 2Fe2+(aq) + 4OH-(aq) The process continue. After that, the Fe2+ and OH- ions will move and diffuse through the water. When both ions meet they will react to produce precipitate which iron (II) hydroxide , Fe(OH)2 .These iron (II) hydroxide then will be further oxidise to iron (II) hydroxide, Fe(OH)3 and will be dehydrated to produce rust. Chemical equation for rusting process : 2Fe(s) + 2H2O(l) + O2(g) > 2Fe2+(aq) + 4OH-(aq) Fe2+(aq) + 2OH-(aq) > Fe(OH)2(s) Fe(OH)2(s) + O2 > Fe(OH)3(s) Fe(OH)3(s) dehydrates > Fe2O3.nH2O(s) or rust Therefore, the chemical formula for rust is Fe2O3.nH2O(s) [5] (Loh Wai Leng,Tan Yin Toon,Tan On Tin, 2011, oxidation and reduction) Acetic acid is a weak acid that presence in vinegar. Vinegar works well than other strong acid because the presence of weak acid. Therefore, it will less attack the iron nail itself. Strong acid will corrode both the rust stain and the iron nail. To prevent that, substance with weak acid is preferable. When the iron nail with rust is soaked into the vinegar containing acid, the rust on iron nail will dissolve and loosen. The crumbly hydrated iron oxide will form a soluble salt, in these reaction between acetic acid and iron(III) oxide, it will formed iron acetate. Equation of reaction between acetic acid and rust: 6CH3COOH(l) + Fe2O3 (s) > 2Fe(CH3COO)3 (s) + 3H2O (l) and ferric acetate, Fe(CH3COO)3 is water soluble. However, the hypothesis for my second experiment is rejected. Clearly from the experiment above, it shows there is no directly proportional relationship between percentage of mass of acetic acid in vinegar and rate of removing rust. Jalen has the highest percentage of mass of acetic acid followed by Earth Brand and Yeos but Earth Brand shows the highest rate of removing rust followed by Jalen and Yeos. There, my experiment has limitation which lead to these result. After the experiment, I accidentally left the iron nail that already washed with vinegar in the cup bottle. I found out that the rusting on iron nail occur more faster by the day. I concluded myself that acid actually can remove the rust stain from the nail but in the same time it also promote rusting. The surface of iron nail will clean after the rust stain is remove and let the iron nail exposed to acid. Somehow, acid will react on the surface of iron nail. Further research could be done to investigate the after effect of acid after removing the rust stain. 5. Conclusion This research show that each vinegar has it own percentage by mass of acetic acid in each and every different type of vinegar. From the experiment and calculation, it shows that the percentage by mass of acetic acid in vinegar brands of Earth Brand, yeos and Jalen accordingly is 85.56%, 83.68% and 92.20%. The difference of percentage by mass of acetic acid in vinegar resulted the difference in the vinegar taste and the pH value. The experiment shows that there is not much significant difference of percentage by mass of acetic acid in different type of vinegar brands. The vinegars used in the experiment is the product of Malaysia . Different result may show if I test of the products of other country. These difference of percentage of acetic acid in different type of vinegar, effect the result obtained in experiment two. The hypothesis for experiment one is accepted. These research also shows that vinegar could serve as a potentially rust stain remover but in low degree because acetic acid presence in vinegar is a weak acid. Still, it could be use safely because the acidic concentration is not harmful and vinegar is easy to obtain rather than any other applications. However , from the result obtain, it shows that the higher the percentage of acetic acid in vinegar, does not always cause higher rate of rust stain removal. Jalen has the highest percentage by mass of acetic acid in vinegar followed by Earth Brand and Yeos which is 92.20%, 85.56% and 83.68% respectively. But the experiment shows that the vinegar that has the highest degree of rust stain removal is Earth Brand followed by Jalen and Yeos which is 0.0049gs-1, 0.0044gs-1 and 0.0043gs-1 second respectively. Therefore I could conclude that , Earth Brand is a better rust stain remover Yeos and Jalen , but Jalen is better than yeos. Even though there is no not much significant difference, but it effected the overall result. Therefore, the hypothesis for the second experiment is not accepted. There is several reason why these result obtained. Maybe there is another substance that presence in the vinegar, react with the rust stain on iron nail which can affect the result because I assumed that the rust stain will only react with the acetic acid presence in vinegar. Further research could be conducted to explain and determine the problem. The other reason may cause due to limitation that will be discuss later. However ,these research able to prove that there is difference of percentage by mass of acetic acid in different type of vinegar and vinegar can act as a potentially rust stain remover . But due to weak acid presence in vinegar, vinegar could only remove rust stain that only form only on surface of metal . It cannot remove the rust that has been deeper into metal . Overall, I can conclude from the experiment that different vinegar has different percentage by mass of acetic acid and vinegar is a highly potential rust stain remover. 6. Evaluation Throughout the experiment there are several limitations that can affect the result of the experiment. During the titration process, The colour of acidic solution which is vinegar, will change from colourless to pale pink at the end of titration process. The perception of colour change will affect the result. It is hard to determine what the exact pale pink colour that need to be achieve. In order to overcome this problem, a controlled conical flask containing acid solution when end point of titration which colour is pale pink should be put beside the set up apparatus so that the person would know what exactly pale pink colour they need to reach. pH meter also can be used to fixed the pH value needed. Another problem that could effect the result is when weighing the weight of iron nail after the rust is formed. Rust that is formed for several days only appear on the surface of the iron nail. Therefore, when removing the iron nail to be weighed, the rust from the surface of iron nail could drop. Even a slight drop of rust from the iron nail, could cause the result obtained will not be accurate . Therefore, to overcome these problem, during the formation of rust, the iron nails should be left on the electronic balance. So, the iron nail does not have to be removed and rust will not fall off. The result obtained will be more precise. Another problem that could arise is when removing the rust from iron nail using vinegar. In these experiment, I assumed that, only acetic acid in vinegar will react with the rust on the iron nail. So that my hypothesis could be achieved. But it turn out my hypothesis is invalid. It could be that other substances presence in the vinegar, will react with the rust on the iron nail. After all, vinegar consist more than one substance. these problem can be overcome by doing some further research. Lastly, the after effect of the experiment. Acid can remove rust stain but the chemical reaction between acid and the surface of iron nail, can increase the rate of rusting of iron nail. Corrosion in acid solutions is much more rapid than in neutral solutions, and the latter is more rapid than in alkaline solutions.[6](Frank N. Neller,2004, Corrosion Facts). Therefore to solve the problem, after washed the iron nail to remove the rust, the iron nail need to place in boil water for a while. Therefore, no after chemical reaction will occur. Thus, rusting will not occur.
