A solution of `CuSO_(4)` is electrolsed for 10 minutes with a current of 1.5 amperes. What is the mass of copper deposited at the cathode ?
(Molar mass of `Cu=63.5 g//mol)`

A

0.492 g

B

0.325 g

C

0.873 g

D

0.296 g

Text Solution

Verified by Experts

The correct Answer is:
D
`Q=Ixxt`
`=1.5xx10xx60`
900C
Reaction occuring at the cathode is
`Cu^(+2)+2e^(-)toCu`
`2F=2xx96500` deposit 1 mole Cu(63.5g)
=0.296g
