What will happen during the electrolysis of aqueous solution of `CuSO_(4)` by using platinum electrodes?

A

Copper will deposit at cathode

B

Copper will deposit at anode

C

Oxygen will be released at anode

D

Copper will dissolve at anode

Text Solution

Verified by Experts

For electrolysis of aqueous solution `CuSO_(4)`
`CuSO_(4)(aq)rarrCu^(2+)+SO_(4)^(2-)`
`H_(@)Orarr2H^(+)+O^(2-)`
At anode `2O^(2-)rarrO_(2)+2e^(-)`
At cathode `Cu^(2+)+2e^(-)rarrCu(s)`
