Question

A solution of sodium sulphate in water is electrolysed using inert electrodes. The products at the cathode and anode are respectively.

Options

A.H2, O2
B.O2, H2
C.O2, Na
D.O2, SO2

Solution

At anode :  2H2O → O2 + 4H+ + 4e-     (not SO42-)
At cathode :  2H2O + 2e- → H2 + 2OH-  (not Na+).
