The electrolytic decomposition of dilute sulphonic acid with platinum electrode in cathodic reaction is
1 Oxidation
2 Reduction
3 Oxidation and reduction both
4 Neutralisation
Explanation:
\(Pt\) electrodes are inert. They won't play any part in the reaction at either electrodes. Dil \(- H _2 SO _4\) implies that both \(H _2 SO _4\) and \(H _2 O\) are involved in the electrolyte. \(H ^{+}\) from \(H _2 SO _4\) and \(H ^{+}\) from \(H _2 O\) will be attracted to the cathode. \(2 H ^{+}+2 e ^{-} \rightarrow H _2\) This is a gain of electrons and so, the reaction is reduction. \(\Rightarrow\) Cathodic reaction in electrolytes of dil. \(H _2 SO _4\) with \(Pt\) electrodes is reduction.
