Quizplus · Accepted Answer

The given redox reaction can be split into two half-reactions: 1. Oxidation half-reaction: 2Fe²⁺ → Fe³⁺ + 2e^- 2. Reduction half-reaction: Cl₂ + 2e^- → 2Cl^- Option I correctly represents the reduction half-reaction by showing the gain of electrons by chlorine ions. Option IV correctly represents the oxidation half-reaction by showing the loss of electrons by iron atoms. Therefore, the correct answer is A.
