An acidic solution of copper (II) sulphate containing some contaiminations of zinc and iron (II) ions was electrolysed till all the copper is deposited. If electrolysis is further continued for sometime, the product liberated at cathode is

A

`Fe`

B

`Zn`

C

`H_(2)`

D

Alloy of Zn and Fe.

Text Solution

Verified by Experts

The correct Answer is:
C
After deposition of `Cu^(2+)` ions `H^(+)` ion from the `H_(2)O` molecule will be discharged at cathode as its SRP is higher than of `Fe^(2+)` and `Zn^(2+)`
