- A Both \((A)\) and \((R)\) are true and \((R)\) is the correct explanation of \((A)\)
- B Both \((A)\) and \((R)\) are true, but \((R)\) is not correct explanation of \((A)\)
- C (A) is true, but ( \(\mathrm{P})\) is talse
- D (A) is false, but (R) is true
Answer & Solution
Correct Answer
(D) (A) is false, but (R) is true
Step-by-step Solution
Detailed explanation
In basic medium \(\mathrm{H}_2 \mathrm{O}_2\) reacts as : \(\mathrm{H}_2 \mathrm{O}_2+2 \mathrm{OH}^{-} \longrightarrow 2 \mathrm{H}_2 \mathrm{O}+\mathrm{O}_2+2 e^{-}\) In alkaline medium \(\mathrm{H}_2 \mathrm{O}_2\) reduces ferricyanide to ferrouscyanide as follows:
