2Cl + 2e⁻ → 2Cl⁻ is the half reaction correctly describes the reduction that is taking place.
The half reaction of overall reaction in which reactants gain its electrons during the reaction is called Reduction Half Reaction.
The half reaction of overall reaction in which reactant loses electrons during the reaction is called Oxidation Half Reaction.
The given reaction is
2I⁻ (aq) + Cl₂ (aq) → 2Cl⁻ (aq) + I₂ (aq)
Reduction Half Reaction: 2Cl + 2e⁻ → 2Cl⁻
Oxidation Half Reaction: 2I⁻ - 2e⁻ → 2I
Here Cl₂ is an oxidizing agent and I⁻ is reducing agent.
Thus from the above conclusion we can say that 2Cl + 2e⁻ → 2Cl⁻ is the half reaction correctly describes the reduction that is taking place.
