Question

Given below are two statements :

Statement I: $S_{8}$ solid undergoes disproportionation reaction under alkaline conditions to form $S^{2 -}$ and $S_{2} O_{3}^{2 -}$

Statement II: ${ClO}_{4}^{-}$ can undergo disproportionation reaction under acidic condition.

In the light of the above statements, choose the most appropriate answer from the options given below:

TestHub · Accepted Answer

A disproportionation reaction is a reaction in which the same element is simultaneously oxidized and reduced. In this type of reaction, a single substance gives two products, one is oxidized while the other is reduced.

$S_{1} : S_{8} + 12 {OH}^{⊝} \to 4 S^{2 -} + 2 S_{2} O_{3}^{2 -} + 6 H_{2} O$

$S_{2} : {ClO}_{4}^{⊝}$ cannot undergo disproportionation reaction as chlorine is present in its highest oxidation state.

Hence, statement $I$ is correct and $II$ is incorrect.
