A current of 0.5 A is passed through a solution of `CuSO_(4)` for 20 min by using platinum electrodes. (1) What amount of copper will be deposited at the cathode ?

Text Solution

Verified by Experts

Quantity of electricity,
`Q=0.5xx(20xx60)=600C.`
`"Equivalent weight of Cu"=(63.5)/(2)=31.75" "[therefore" valency of Cu in "CuSO_(4)=2]" and that of oxygen "=(16)/(2)=8.`
`"So, 600 C of electricity will deposit "(31.75xx600)/(96500)=0.1974g` of Cu at the cathode.
