H2 is liberated at cathode while O2 is liberated at anode.

Q. A solution of $N a_{2} S O_{4}$ in water is electrolysed using Pt electrodes. The products at the cathode and anode are respectively, ?

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

$O_{2}, N a O H$

$H_{2}, O_{2}$

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

$H_{2}$ is liberated at cathode while $O_{2}$ is liberated at anode.
