`1L` of `1M CuSO_(4)` solution is electrolyzed using `Pt` cathode and `Cu` anode. After passing `2F` of electricity, the `[Cu^(2+)]` will be

A

0

B

`M`

C

`M//2`

D

`M//4`

Text Solution

Verified by Experts

The correct Answer is:
b
`[Cu^(2+)]` will remain same since `CuOS_(4)(aq)` is being electrolyzed using `Cu` anode.
