To deposit `0.6354 g` of copper by electrolysis of aqueous cupric sulpbate solution, the amount of electricity required (in coulmmbs) is.

A

9650

B

4825

C

3860

D

1930

Text Solution

Verified by Experts

The correct Answer is:
D
`Cu^(++)+2e^(-)Cu`
`E_(Cu)=(63.54)/(2)=31.77`
Amount of electricity required to deposit 0.6354gm of Cu `=(96500xx0.6354)/(31.77)=1930` coulomb.
