Background information on Electrolysis Electrolysis is a chemical process by which electrical currents can be passed through solutions. Pure water cannot conduct electricity, but if a salt such as Sodium Chloride is dissolved in it, the solutions will start conducting if two electrodes are placed in it with a battery that provides the initial current. When we close the switch, copper ions on the anode will start to move through the solution to the cathode. The copper atoms have already given up two electrons to become ions and their electrons are free to move in the wires. Closing the switch pushes electrons clockwise and forces some copper ions into the solution. The cell pushes the ions from the anode to the cathode. At the same time, it pushes the free electrons around the wires (these electrons are already spread through the wires). Electrons in the cathode recombine with copper ions from...
