Both Mg and Fe metal can reduce copper from a solution having Cu²⁺ ion, according to equilibria.

Mg_(s) + Cu²⁺ $\rightleftharpoons$ Mg²⁺ + Cu_(s); K₁ = 6 x 10⁹⁰

Fe_(s) + Cu²⁺ $\rightleftharpoons$ Fe²⁺ + Cu_(s); K₂ = 3 x 10²⁶

Choose the correct option regarding above equilibrium

• Mg removes more Cu²⁺ from solution

• Fe removes more Cu²⁺ from solution

• Both will equally remove Cu²⁺ from solution

• Both metals cannot remove Cu²⁺ from solution
