Which is correct increasing order of deposition? (1) Na+ < Mg+2 < Zn+2 < Ag+ (2) Ag+ < Zn+2 < Mg+2 < Na+ (3) Mg+2 < Na+ < Zn+2 < Ag+ (4) Mg+2 < Zn+2 < Na+ < Ag+

Answer»

Correct option (1) Na+ < Mg+2 < Zn+2 < Ag+

Explanation:

Increasing order of deposition is related to the order of reduction and oxidation potential (in accordance with preferential discharge theory)

Na+ < Mg+2 < Zn+2 < Ag
