A certain current liberates `0.5g` of hydrogen in 2 hours. How many grams of copper can be liberated by the same current flowing for the same time in a copper sulphate solution ?

A

31.8g

B

63.6g

C

15.9g

D

6.36g

Text Solution

Verified by Experts

The correct Answer is:
A
g eq. of hydrogen =g eq. of Cu
`(0.504)/(1)=(W)/(63.5//2) therefore W=15.9g`
