A solution of `CuSO_(4)` is electroysed 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)`

Text Solution

Verified by Experts

`I=1.5" Ampere"`
`"Time "=10xx60s=600s`
`Q=Ixxt`
`=1.5xx600=900C`
`Cu^(2+)+2e^(-)rarrCu(s)`
2F amount of electricity deposit copper = 63.5 g
`"900 C amount of electricity deposit copper"=(63.5xx900)/(2xx96500)`
`=0.296g`
