Anode
Explanation
Electrolysis is a process that uses an electric current to drive a non-spontaneous chemical reaction. The process occurs in a setup known as an electrolytic cell, which consists of two electrodes: an anode and a cathode. Important to note in this cell is the nature of the reaction that occurs at each electrode. At the anode, oxidation occurs. Oxidation is the process by which a molecule, atom, or ion loses electrons. Therefore, during electrolysis, the electrode at which oxidation occurs is the anode.
