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."

The purpose for this lab was to use aluminum from a soda can to form a chemical compound known as hydrated potassium aluminum sulfate. In the lab aluminum waste were dissolved in KOH or potassium sulfide to form a complex alum. The solution was then filtered through gravity filtration to remove any solid material. 25 mLs of sulfuric acid was then added while gently boiling the solution resulting in crystals forming after cooling in an ice bath. The product was then collected and filter through vacuum filtration. Lastly, crystals were collected and weighed on a scale.
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.

The iPhone is one of the world's bestselling smartphones, but it could probably win more market share if its price fell. However, It must find the right balance price and quality as it attempts to do so to become more accessible.

Chemistry is used in our everyday life in more ways than we may think. One way that we use chemistry is in the batteries in our cell phones. They are solely responsible for the phone actually turing on and being powered to run. Most cell phones are powered with a rechargeable Lithium-ion battery. Lithium-ion batteries are commonly used in digital cameras and even in electric cars. These batteries are made of lithium cobalt cathode and carbon anode.
