How much quantity of electricity has to be passed through 200 ml of 0.5 M `CuSO_(4)` solution to completely deposit copper ?

A

`9.65xx10^(4)C`

B

`1.93xx10^(4)`

C

`3.86xx10^(5)`C

D

`2.895xx10^(5)C`

Text Solution

Verified by Experts

The correct Answer is:
B
Moles of `CuSO_(4)`
`=(200xx0.5)/(1000)=0.1` mol
Charge required to convert `0.1 M Cu^(2+)` to
`Cu=2xx96500xx0.1`
`=1.93xx10^(4)`
