Reduction

Vedclass · Answer

(B) $Pt$ electrodes are inert and do not participate in the reaction at either electrode.Dilute $H_{2}SO_{4}$ contains $H^{+}$ ions from both $H_{2}SO_{4}$ and $H_{2}O$.At the cathode,$H^{+}$ ions gain electrons to form hydrogen gas:$2H^{+} + 2e^{-} \rightarrow H_{2}(g)$Since this process involves the gain of electrons,it is defined as a reduction reaction.Therefore,the cathodic reaction in the electrolysis of dilute $H_{2}SO_{4}$ with $Pt$ electrodes is reduction.

The electrolytic decomposition of dilute sulphuric acid with $Pt$ electrodes in the cathodic reaction is:
