At cathode: 2 H ++2 e- longrightarrow H 2 At anode: 2 OH - longrightarrow H 2 O +1 / 2 O 2+2 e-

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

$H_{2}, O_{2}$

$O_{2}, H_{2}$

$O_{2}, N a$

$O_{2}, S O_{2}$

At cathode : $2 H^{+} + 2 e^{-} ⟶ H_{2}$

At anode $: 2 O H^{-} ⟶ H_{2} O + 1/2 O_{2} + 2 e^{-}$
