2CL-(aq) → CI2(g) + 2e-(aq). The above half-cell reaction occuring at the anode during the electrolysis of dilute ZnCI2 solution is?

Answer Details

The given chemical equation represents a half-cell reaction that occurs at the anode during the electrolysis of dilute ZnCl2 solution. In this reaction, 2 chloride ions (2Cl-) in the aqueous solution lose 2 electrons (2e-) each and get converted into chlorine gas (Cl2). Therefore, the half-cell reaction is an oxidation reaction because the chloride ions are losing electrons and getting oxidized to form Cl2 gas. Hence, the correct option is "oxidation."
