Question

What decides if an electrode is an anode or a cathode?

Answer 1

When the cell is being charged, the anode becomes the positive (+) and the cathode the negative (−) electrode. This is also the case in an electrolytic cell. When the cell is being discharged, it behaves like a primary cell, with the anode as the negative and the cathode as the positive electrode.

Answer 2

Explanation:

When an electrode is oxidized in a solution, it is called an anode and when an electrode is reduced in solution. it is called a cathode.
