The answer is: sodium (Na) and iodine (I₂). First links ion in this salt are separated because of heat: NaI(l) → Na⁺(l) + I⁻(l).The reduction reaction at the cathode(-): Na⁺(l) + e⁻ → Na(l) /x 2.2 Na⁺(l) + 2e⁻ → 2Na(l).The oxidation reaction at the anode(+): 2I⁻(l) → I₂(l) + 2e⁻.The anode is positive and the cathode is negative.
