Question
State the name of the ion which is oxidised in the following half equations.Cathode: Na+ + e– → Na Anode: 2Cl– → Cl2 + 2e–
Solution
The ion that is oxidized in the given half equations is Cl-. Oxidation is the process of losing electrons. In the anode half equation, 2Cl- loses 2 electrons to form Cl2, which is a clear indication of oxidation.
