Electrolysis is the process in which a chemical is broken down into its component chemicals using electricity. It involves submerging two metal electrodes into a liquid or molten substance that contains positive and negative ions.
The electrodes connect to a battery. When they are electrically charged, one electrode becomes the negative terminal or cathode, and the other becomes the positive terminal or anode. The positive terminal attracts negatively charged ions and the negative terminal attracts positively charged ions.
