I₂ gas is formed at anode and Magnesium liquid is formed at cathode.
The half reaction of overall reaction in which reactant loses electrons during the reaction is called Oxidation Half Reaction.
The half reaction of overall reaction in which reactants gains its electrons during the reaction is called Reduction half reaction.
The possible oxidizing agents in KI and MgF₂ are K⁺ and Mg⁺². The possible reducing agents in KI and MgF₂ are I⁻ and F⁻.
Reduction: Mg⁺² (l) + 2e⁻ → Mg (l)
Oxidization: 2I⁻ (l) → I₂ (g) + 2e⁻
Overall cell reaction is:
Mg⁺² (l) + 2I⁻ (l) → Mg (l) + I₂ (g)
Thus from the above conclusion we can say that I₂ gas is formed at anode and Magnesium liquid is formed at cathode.
