To deposit 0.6354 g of copper by electrolysis of aqueous cupric sulphate solution, the amount of electricity required (in Coulombs) is

A

9650

B

4825

C

3860

D

1930

Text Solution

Verified by Experts

The correct Answer is:
D
`Cu^(2+)+2e^(-)toCu`
`E_(Cu)=63.54/2=31.77`
Amount of electricty requird to deposit 0.6354 g of Cu
`=(96500xx0.6354)/31.77` =1930 coulombs
