(a) Zn occurs readily as ion whereas Cu occurs more readily as metal in nature.

(b) Copper is above silver in the electrochemical series and is thus more reactive than silver. So, copper displaces silver from silver nitrate. Hence, we cannot store AgNO3 solution in copper vessel.

Cu + AgNO3 → Cu(NO3)2 + 2Ag

(c) Copper is more active than Ag.
