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 gB. 0.325 gC. 0.873 gD. 0.296 g

Answer» Correct Answer - 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
