Summary: In Experiment number eleven we focused on the electroplating process and the measurement of Avogadro's number. Electrolysis is a process in which electrical energy is used in order to force a chemical reaction to occur between two or more elements that don't, under normal circumstances, bond. Electrolysis can also be used to extract an element from it's ore. In this experiment we used a strip of copper and a strip of tin to perform the electrolysis. What we did was run a current through each of our strips inside a beaker filled with Tin Chloride which conducts electricity. After turning on the experiment, we immediately observed some changes on the copper and tin. The tin began to discolor throughout the experiment and the copper began to collect a build up of tin on it's surface. After a sufficient amount of time, we stopped the experiment and weighed our strips. After following the calculations I came up with fairly close experimental value for
