A current of `965A` is passed for `1 s` through `1L` solution of `0.02N NiSO_(4)` using `Ni` electrodes. What is the new concentration of `NiSO_(4)` ?

A

`0.01N`

B

`0.01M`

C

`0.003M`

D

`0.02M`

Text Solution

Verified by Experts

The correct Answer is:
b
`(W)/(E_(w))=(965xx1)/(96500)=0.01`
Equivalent of `NiSO_(4)` present initially `=1xx0.02=0.02` If `Ni` electrodes are used no change in concentration of `NiSO_(4),i.e., 0.02N or 0.01M`.
If `Pt` electrodes are used, then equivalent of `NiSO_(4)` left `=0.01`
