A certain current liberates 0 . 5 g 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" H_(2))/("Ew of" H_(2))=("Weight of " Cu)/(" Ew of Cu)`
`(0.5)/(1)=(x)/(63.5//2)`
`thereforex=15.9g`
