Redox Reactions Question 10
Question 10 - 2024 (31 Jan Shift 2)
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 :
(1) Statement I is correct but statement II is incorrect.
(2) Statement I is incorrect but statement II is correct
(3) Both statement I and statement II are incorrect
(4) Both statement I and statement II are correct

Answer (1)
Solution
$S _1: S _8+12 OH^{\ominus} \rightarrow 4 S^{2-}+2 S _2 O _3^{2-}+6 H _2 O$
$S _2: ClO _4^{\ominus}$ cannot undergo disproportionation reaction as chlorine is present in it’s highest oxidation state.
