If the aqueous solutions of the following salts are electrolysed for 1 hour with 10 ampere current, which solution will deposit the maximum mass of the metal at cathode ? The atomic weights are : `Fe=56, Zn=65, Ag=108, Hf=178` and `W=184`.

A

`ZnSO_(4)`

B

`FeCl_(3)`

C

`HfCl_(4)`

D

`AgNO_(3)`

Text Solution

Verified by Experts

The correct Answer is:

D

Greater is the equivalent mass of the metal more will be the amount deposited at cathode.

`:.` Maximum amount of silver will be deposited at cathode.
