Question

In the reaction 2H2O (l) + 2Cl– (aq) → H2 (g) + Cl2 (g) + 2OH– (aq), which substance is oxidized?

Answer 1

F. None of the above [Cl^(-) is oxidized]

No Cl atoms are available to be oxidized, only Cl^(-)ions

2Cl^(-) → Cl_2 + 2e^(-)

The substance that loses electrons is oxidized.

Remember OIL RIG (Oxidation Is Loss of electrons) and

LEO the lion says GER (Loss of Electrons is Oxidation).
