Question

BY the electrolysis of aqueous solution of CuSO4, the products obtained at both the electrodes are

Options

A.O2 at anode and H2 at cathode
B.H2 at anode and Cu at cathode
C.O2 at anode and Cu at cathode
D.H2S2O8 at anode and O2 at cathode

Solution

at anode     2H2O → O2 + 4H+ + 4e-
at cathode   Cu2+ + 2e- → Cu
