Introduction The purpose of this experiment is to show how an acid (Coke) can react together with potassium to create a charger for an iPhone. Potassium and acid formed together makes bubbles. With both potassium and acid working together, they will give off energy to the iPhone. Why Coke? Every liquid will be either acidic or basic traits. An acid-base reaction is a chemical reaction that happens between an acid and a base. There are multiple definitions when considering the reaction mechanism when solving problems. Regardless of what the problem is, it’s always a known fact that when using liquid or gaseous reactions, they become less apparent. You want to use Coke because its pH is the acidity of the substance. For an acidity to be considered neutral, and has to have a pH balance of 7 or somewhere around 7. It ranges from acids to bases. Coke is an acidic because its carries a pH balance of 2.525, meaning it is very corrosive. Because Coke is an acid, it’s very easy for it to function as a decaying tool. Some say that Coke can be considered very dangerous because it can do such things as cause tooth decay, rust nails, and clean toilets, but truth is, Coke is a very big reactive acid that is consumed by millions of people on a regular basis. Equipment Whether people know it or not, chemical reactions happen all the time in everyday life experience. Some you can see just by looking at them and others are a little bit difficult to determine. One might ask, well, what is a chemical reaction and how did this idea come about? Based off of many studies and experiments, Luis Istolar is the scientists that discovered a chemical reaction. A chemical reaction is defined as a reaction in which the composition of a substance and/or elemen... ... middle of paper ... ...=W/∆t. Now, we know that there is an electric potential difference between the positive and the negative terminals of a battery, so the charge loses electric potential energy as it moves from the positive end (higher electric potential) to the negative end (lower electric potential (there is a work done here), so electric power for our iPhone can be calculated using the ratio of change in energy and the time interval: P=(∆q(V))/∆t or P=IV Works Cited "Apple - iPhone - Compare Models."

When a solution conducts electricity, the charge is carried by ions moving through a solution. Ions are atoms or small groups of atoms that have an electrical charge. Some ions have a negative charge and some have a positive charge. Pure water contains very few ions, so it does not conduct electricity very well. Not all substances are made up of ions. Some are made of uncharged particles called molecules. Sugar is such a substance. When sugar is dissolved in water, the solution does not conduct electricity, because there are no ions in the solution. That's why in Hands-on Squishy Circuits, the sugar PLAY-DOH did not produce electricity. The salt had ions in it to produce the electricity needed to make the LEDs light up.

In an “electrolytic solution”, if two electrodes, one being positive and the other negative, are placed in the solution then ions have the ability to transport free electrons to and from both of the electrodes. Acids in a solution are good electrolytes since the acids supply the solution with hydrogen ions. If a solution contains organic compound has sugar or starch, then that solution won’t conduct electricity well since organic compounds are contributing as many hydrogen ions as acids. The most familiar electrolytes would be elements such as potassium, calcium, sodium, and magnesium. Lithium-ion batteries are commonly used in many household as a source of energy, however the battery relies heavily on liquid electrolytes which are flammable and are prone to fires.Researchers at Oak Ridge National Laboratory has created a solid electrolytes that is made out of lithium triphosphate to try to overcome the safety issues presented by lithium-ion
The Purpose of the Chemical Reaction Lab was to examine and measure the chemical reaction of H-C-L, hydrochloric acid and CuCl2, Copper chloride solution to determine different types of reactions, within specific elements and compounds; Aluminum foil, Al aluminum shot, Ammonium hydroxide, Magnesium, Silver nitrate, Sodium carbonate, Sodium bicarbonate, Sodium hydroxide, and Zinc. By completing the trials, the data displayed chemical changes. These changes were observable in changes of substances, such as formation of precipitate, change in color, release of gas, and difference of temperature.
All in all, Lithium-Ion Batteries help power the world to become more efficient and effective. These batteries power up the portable gadgets that the world takes for granted and they help foster communication and education around the world. While every portable gadget might be different in every way, one thing will always be the same among those gadgets and that is the Lithium-Ion Battery.
A battery is a device which converts chemical energy into electrical energy. A battery usually consists of two or more cells connected in series or parallel, you can also have a single cell battery. All cells consist of a positive electrode, and a negative electrode. An electrolyte is a liquid substance capable of conducting electricity. In this substance one of the electrodes will react producing electrons, while the other will except electrons. When the electrodes are connected to a device to be powered, called a load, an electrical current flows.
“A chemical reaction is a change that makes at least one new substance,” according to Richard Spilsbury (2014, p. 8) A physical reaction is when you mix two or more substances and those substances stay the same. This experiment demonstrates a physical reaction called ‘nucleation.’ The rough surface of the Mentos and the carbon dioxide inside the soda combine together to make the soda explode! This is not a chemical reaction because we do not make a new substance. “In physical changes, the original substances do not change chemically. For example, you can dissolve salt in water to make salty solution,” according to Richard Spilsbury (2014, p. 13). In this case, you still have salt and water, not a new product. With Diet Coke and Mentos, you still have these two substances in a much messier form, but you do not have a new
...t. This effect is often seen when a battery is recharged before it has been completely discharged. Over time, this cycle causes the battery to “remember” the lower energy capacity which results in an incomplete charge. This effect comes into play when a battery is discharged to the same point repeatedly and then recharged. This causes a chemical difference between the active and inactive layers of conductive material. The result of this is reduced battery life at the point which the cell is usually recharged.

When you mix baking soda and vinegar you get what’s called a chemical reaction. A chemical reaction is the process by which one or more substances change to produce one or more different substances (blue book). In this case, you would be mixing an acid and a base. The tw...
