Transcript of Vinegar Battery

CHAPTER ITHE PROBLEM AND ITS BACKGROUND

IntroductionThe world is blessed by the abundance of energy. It comprises various types of energy. One of this is electrical energy or electricity. Electricity is one of the most powerful forces in our lives.This term makes us to remind of that anything that an individual plug into the outlet, an electric current will flow to the device. It is the key component for the modern society everyone has today. Without this, our world is totally different.People continue to prosper the knowledge of producing electricity. As the result, inventions of electricity-producing products are made. Since its invention, the battery has become the most common power source for many household and industrial applications. A battery converts chemical energy to electrical energy. Each cell contains positive terminal, cathode and negative terminal, anode. There are many ways to construct a battery, as well as ways to control its generated output. Each component is highly needed to produce the expected outcome of the endeavor. It shows that searching new ways of producing electricity is not possible. Its also impressive to know how vinegar can produce electricity and how it will help the environment. With this research, each individuals curiosity will be captivated.

Background of the Study

To widen our knowledge about generating new source of electrical energy, the researchers come up with an idea to prove other alternative basis of electricity. They arrived to ascertain the vinegar battery that can generate electricity. The basic principles of positive and negative charges can be demonstrated by making a simple battery like this. This experimental set-up uses the positive and negative ions from the copper and zinc. When the electrodes (copper and zinc) are immersed in vinegar, they draw ions from the vinegar, and the movement of the ions creates an electrical current.The researchers prioritize not only the discovery of the vinegar battery as an alternative source but also as renewable source of energy. A vinegar battery may not be as strong as other commercial batteries. However, this is cheaper than other batteries. After all, vinegar is freely available anywhere. It is also environmental friendly because it doesnt contain hazardous and toxic elements. This is something that seems like magic to most people, but is really simple science. This energy if guided correctly can power devices.

Discover the effectiveness of vinegar battery, in terms of:a) Voltage productionb) Number of devicesc) Life span of materials usedHypothesis1. Vinegar does not conduct electricity.2. Vinegar, copper strip and galvanized nails are not related to each other. 3. Overall, vinegar battery is not effective as an alternative source of electrical energy.

Significance of the Study

Nowadays, many scientists are doing several researches to overcome the energy crisis. All of us will experience a great loss about that. People used to be in the world of having electricity. As a result, it would be a dilemma for everybody.Electrical energy provides us the easiness in doing different things. Everyone use this in everyday life. It is used throughout the world in giving power for every appliance each have. It gives the amusement and swept out the boredom. And also, comfort to an individual who is displeased of something. Because of wanting to satisfy everything easily, people depend to the things theyre used to. They forgot that they have capabilities to make solutions to simple things. This study opens each mind that everyone can make their own way in simplifying problems. By this, people will have the knowledge on what to do if the time comes. It is very important to obtain an idea for everything.

Scope and Limitation of the Study

The concentration of the study is all about the usefulness and effectiveness of the vinegar battery in forming electrical energy to devices such as digital clock and calculator.

Definition of Terms

Electrical energy It is the energy carried by moving electrons in an electric conductor. It cannot be seen, but it is one of our most useful forms of energy because it is relatively easy to transmit and use. All matter consists of atoms, and every atom contains one or more electrons, which are always moving. When electrons are forced along a path in a conducting substance such as a wire, the result is energy called electricity.Battery Or a cell that converts chemical energy to electrical energy through positive and negative terminal.Vinegar Produces free ions in solution.Galvanized nails (Zinc) Serves as negative terminal of the battery.Copper Serves as positive terminal of the battery.

CHAPTER IIREVIEW OF RELATED LITERATURE AND STUDIESThis chapter presents the related literature and studies from foreign or local. Through this, additional information to widen researchers idea is observed. Also, it leads as the basis of the study, The Effectiveness of vinegar as a battery.Related LiteratureInvention of BatteryThe making of battery was such a phenomenal success after all the different scientists been through. Voltas experiment and study brought us today the battery. As time goes by, different kinds were made and improved.It all started in 1780 when Luigi Galvaniwas dissecting a frog affixed to abrasshook. When he touched its leg with his iron scalpel, the leg twitched. He believed the energy that drove this contraction came from the leg itself, and called it "animal electricity".However,Alessandro Volta, his friend and fellow scientist, disagreed, believing this phenomenon was caused by two different metals joined together by a moist intermediary. He verified this hypothesis through experiment, and published the results in 1791. In 1800, Volta invented the first true battery, which came to be known as thevoltaic pile. Thevoltaic pileconsisted of pairs ofcopperandzincdiscs piled on top of each other, separated by a layer of cloth or cardboard soaked inbrine(i.e., theelectrolyte). Unlike theLeyden jar, the voltaic pile produced a continuous and stable current, and lost little charge over time when not in use, though his early models could not produce a voltage strong enough to produce sparks.He experimented with various metals and found that zinc and silver gave the best results.Volta believed the current was the result of two different materials simply touching each otheranobsolete scientific theoryknown as contact tensionand not the result of chemical reactions. As a consequence, he regarded the corrosion of the zinc plates as an unrelated flaw that could perhaps be fixed by changing the materials somehow. However, no scientist ever succeeded in preventing this corrosion. In fact, it was observed that the corrosion was faster when a higher current was drawn. This suggested that the corrosion was actually integral to the battery's ability to produce a current. This, in part, led to the rejection of Volta'scontact tension theoryin favor of electrochemical theory. Volta's illustrations of his Crown of Cups and voltaic pile have extra metal disks, now known to be unnecessary, on both the top and bottom. The figure associated with this section, of the zinc-copper voltaic pile, has the modern design; an indication that contacts tension" is not the source ofelectromotive forcefor the voltaic pile.Volta's original pile models had some technical flaws, one of them involving theelectrolyteleaking and causing short-circuits due to the weight of the discs compressing the brine-soaked cloth. A Scotsman namedWilliam Cruickshanksolved this problem by laying the elements in a box instead of piling them in a stack. This was known as thetrough battery.Volta himself invented a variant that consisted of a chain of cups filled with a salt solution, linked together by metallic arcs dipped into the liquid. This was known as the Crown of Cups. These arcs were made of two different metals (e.g., zinc and copper) soldered together. This model also proved to be more efficient than his original piles,though it did not prove as popular.Another problem with Volta's batteries was short battery life (an hour's worth at best), which was caused by two phenomena. The first was that the current produced electrolyzed the electrolyte solution, resulting in a film ofhydrogenbubbles forming on thecopper, which steadily increased the internal resistance of the battery (This effect, calledpolarization, is counteracted in modern cells by additional measures). The other was a phenomenon calledlocal action, wherein minute short-circuits would form around impurities in the zinc, causing the zinc to degrade. The latter problem was solved in 1835 byWilliam Sturgeon, who found that amalgamated zinc, whose surface had been treated with somemercury, didn't suffer from local action. Despite its flaws, Volta's batteries provided a steadier current than Leyden jars, and made possible many new experiments and discoveries, such as the first electrolysis of water by Anthony Carlisle and William Nicholson. *Source: WikipediaRelated StudiesSaltwater BatterySalt molecules are made of sodium ions and chlorine ions. (Anionis an atom that has an electrical charge because it has either gained or lost an electron.) When you put salt in water, the water molecules pull the sodium and chlorine ions apart so they are floating freely. These ions are what carry electricity through water. *Source: Home Science ToolsA.
