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+).
At cathode : 2H2O + 2e- → H2 + 2OH- (not Na+).
