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

12.7 g

B

15.9 g

C

31.8 g

D

63.5 g

Text Solution

Verified by Experts

The correct Answer is:
B
`("Weight of Cu")/("Weight of" H_2)=("Eq. weight of Cu")/("Eq. weight. of H")`
`("Weight of Cu")/(0.50)=(63.6//2)/1`
Weight of Cu= 15.9 g.
