To deposits 0.634 g of copp·er by electrolysis of aqueous cupric sulphate solution the amount of electricity required (in coulombs) 0 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= `(96500xx0.634)/(31.7)=1930C`
