If electrolysis of aqueous CuSO_(4) solution is carried out using Cu- electrons, the reaction taking place at the anode is

Answer»

`H^(+) + e^(-) rarr H`
`Cu_((AQ))^(2+) + 2e^(-) rArr Cu_(s)`
`SO_(4(aq))^(2-) -2e^(-) rarr SO_(4)`
`Cu_(s) -2e^(-) rarr Cu_((aq)^(2+)`

Solution :THEREACTIONS occuring at the electrodes are as follows :
At cathode , `Cu_((aq))^(2+) + 2e^(-1) rarr Cu_((s))`
copper dissolves into the solution from the anode and is deposited at the cathode.
