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

A. H2O

B. Cl

C. H

D. OH

E. None of the Above (This is not a redox reaction.)

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).
