Both Mg and Fe metal can reduce copper from a solution having Cu2+ ion, according to equilibria.
Mg(s) + Cu2+ Mg2+ + Cu(s); K1 = 6 x 1090
Fe(s) + Cu2+ 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
