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

3960

D

1930

Text Solution

Verified by Experts

The correct Answer is:
D
Atomic weight of copper = 63.4
Equivalent weight of copper = 63.4/2 = 31.7
` because ` 31.7 g of Cu is deposited by 96500 C
` therefore ` 1 g of Cu is deposited by= `(96500)/(31.7)`
` therefore ` 0.634 g of Cu is deposited by ` = (96500 xx 0.634)/(31.7) = 1930C`
