During the electrolysis of the aqueous solution of copper sulphate using Pt electrodes , the reaction taking place at anode electrode is

A

`Cu^(2+)+2e^(-)toCu`

B

`Cu to Cu^(2+)+2e^(-)`

C

`2H_(2)O to4H^(oplus)+O_(2)+4e^(-)`

D

`H_(2)O+e^(-) to overset(Theta)(OH)+1//2H_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
At anode oxidation of `H_(2)O` occurs since the oxidation potential of `H_(2)O` is greater than the oxidation potential of `SO_(4)^(2-)` ion .
