In the electrolysis of aqueous solutoin of copper suphate using copper

1.	In the electrolysis of aqueous solutoin of copper suphate using copper stirps as anode and cathode the anode rection is
Answer» `Cu^(2+)+2e^(-)rarrCu` `CurarrCu^(2+)+2e^(-)` `2HO^(-)rarrH_(2)+1//2O_(2)+2e^(-)` `2HSO_(4)^(-)rarrH_(2)S_(2)O_(8)+2e^(-)` Solution :At ANODE oxidation occur the possible reactionwhich may occur at anode are `Cu(s)rarrCu^(2)+2E^(-)+2E^(-),E^(@)=-0.80 v` `2H_(2)O(l)rarrO_(2)(g)+4H^(+)(AQ)+4E^(-),E^(2)=-1.23` V since oxidation potential of Cu ishigher than that of`H_(2)O` melecules thus OPTION (b) is correct
