IntroductionThe purpose of this experiment is to show how an acid (Coke) can react with potassium to create a charger for an iPhone. Potassium and acid formed together form bubbles. Working together, the potassium and acid will give energy to the iPhone. Why Coke? Each liquid will have acidic or basic characteristics. An acid-base reaction is a chemical reaction that occurs between an acid and a base. There are several definitions when considering the reaction mechanism when solving problems. Whatever the problem, it is still a known fact that when liquid or gas reactions are used, they become less apparent. You want to use Coca-Cola because its pH matches the acidity of the substance. For an acidity to be considered neutral, it must have a pH of 7 or somewhere around 7. This ranges from acids to bases. Coke is acidic because its pH is 2.525, which means it is very corrosive. Since Coca-Cola is an acid, it is very easy for it to function as a decomposition tool. Some say that Coke can be considered very dangerous because it can cause tooth decay, rust on nails and clean toilets, but the truth is that Coke is a very large reactive acid that is consumed regularly by millions of people. EquipmentWhether people know it or not, chemical reactions occur all the time in everyday life. Some are visible just by looking at them and others are a little difficult to determine. One might ask: what is a chemical reaction and how did this idea come about? Based on numerous studies and experiments, Luis Istolar is the scientist who discovered a chemical reaction. A chemical reaction is defined as one in which the composition of a substance and/or element...... middle of paper ......=W/∆t. Now, we know that there is an electric potential difference between the positive and negative terminals of a battery, so the charge loses electric potential energy as it moves from the positive end (higher electric potential ) at the negative end (lower electric potential (there is some work done here), so electric power of our iPhone can be calculated using the energy change ratio and time interval: P=(∆ q(V))/∆t or P=IVWorks cited "Apple - iPhone - Compare Models, nd Web May 10, 2014.
