- B Reaction of acidified \(\mathrm{KMnO}_4\) with \(\mathrm{H}_2 \mathrm{O}_2\)
- C Reaction of iodine with \(\mathrm{H}_2 \mathrm{O}_2\) in basic medium
- D Reaction of lead sulphide with \(\mathrm{H}_2 \mathrm{O}_2\)
Answer & Solution
Correct Answer
(D) Reaction of lead sulphide with \(\mathrm{H}_2 \mathrm{O}_2\)
Step-by-step Solution
Detailed explanation
(i) \(2 \mathrm{HOCl}+\mathrm{H}_2 \mathrm{O}_2 \longrightarrow 2 \mathrm{H}_2 \mathrm{O}+\mathrm{Cl}_2(g)+\mathrm{O}_2(g)\) (ii) \(3 \mathrm{H}_2 \mathrm{O}_2+2 \mathrm{KMnO}_4 \longrightarrow 3 \mathrm{O}_2+2 \mathrm{MnO}_2\) \(+2 \mathrm{KOH}+2 \mathrm{H}_2 \mathrm{O}\) (iii)…
