$H_2$ is evolved at the cathode.

Vedclass · Answer

(A) During the electrolysis of dilute $H_2SO_4$ using platinum electrodes,the following reactions occur:At the cathode: $2H^+ (aq) + 2e^- \rightarrow H_2 (g)$At the anode: $2OH^- (aq) \rightarrow \frac{1}{2} O_2 (g) + H_2O (l) + 2e^-$Thus,$H_2$ gas is evolved at the cathode and $O_2$ gas is evolved at the anode. Therefore,option $A$ is correct.
