Both Mg and Fe metal can reduce copper from a solution having Cu ²⁺ ion, according to equilibria. aligned & Mg _ (s) + Cu ²⁺ Mg ²⁺+ Cu _ (s) ; K₁=6 10⁹⁰ & Fe _ (s) + Cu ²⁺ Fe ²⁺+ Cu _ (s) ; K₂=3 10²⁶ aligned Choose the correct option regarding above equilibrium

Options

  1. AMg removes more Cu ²⁺ from solution
  2. BFe removes more Cu ²⁺ from solution
  3. CBoth will equally remove Cu ²⁺ from solution
  4. DBoth metals cannot remove Cu ²⁺ from solution

Correct answer

A. Mg removes more Cu ²⁺ from solution

Step-by-step solution

Since, K₁ K₂ , the product in the first reaction is much more favoured than in the second one. Mg thus removes more Cu ²⁺ from solution than Fe does.
