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

`Q=ixxt`
`=1.5xx10xx60`
`=1.5xx600=900C`
Reaction ocuring at the cathode is
`(Cu^+2)+2e^(-1)rarrCu`
2F=`2xx9500` C deposit Cu =1 mole = 63.5 g
900 C will deposit Cu `=(63.5)/(2xx96500)xx900=0.296 g`
