When molten ICl3 is electrolysed using platinum electrodes — Electrochemistry Chemistry Question

💡 Solution & Explanation

Molten ICl3 auto-ionizes into ICl2^+ and ICl4^-. During electrolysis, the cation ICl2^+ migrates to the cathode where the less electronegative element (Iodine in a positive oxidation state) gets reduced to form I2. The anion ICl4^- migrates to the anode where the more electronegative element (Chlorine) gets oxidized to form Cl2 gas. Therefore, correct answer is A.
