1.	During the electrolysis of the aqueous solution of copper sulphate using `Pt` electrode, the reaction taking place at anode electrode isA. `Cu^(2+)+2e^(-) rarr Cu`B. `Cu rarr Cu^(2+)+2e^(-)`C. `2H_(2)O rarr 4H^(o+)+O_(2)+4e^(-)`D. `H_(2)O+e^(-) rarr overset(c-)(O)H+1//2H_(2)`
Answer» Correct Answer - c At anode oxidation of `H_(2)O` occurs since the oxidation potential of `H_(2)O` is greater than the oxidation potential os `SO_(4)^(2-)` ion.
