Question

Statement-I : \(\mathrm{KMnO_4}\) is a good reducing agent.
Statement-II : \(\mathrm{KMnO_4}\) reduces nitrite, oxalate and iodide ions.

• A. Both statements are correct.
• B. Both statements are incorrect.
• C. Statement I is correct while Statement II is incorrect.
• D. Statement I is incorrect while Statement II is correct.

Hint:

\(\mathrm{KMnO_4}\) almost always acts as an {oxidizing agent}. If a statement says it is reducing something, check carefully!

Answer 1

The Correct Option is B

Concept:
\(\mathrm{KMnO_4}\) (potassium permanganate) is a strong oxidizing agent
, not a reducing agent. Its reactions depend on the medium (acidic, neutral, or alkaline). Statement-wise Analysis:
Statement-I:
{\(\mathrm{KMnO_4}\) is a good reducing agent.}

\(\mathrm{KMnO_4}\) readily gains electrons (Mn\(^{+7}\) is reduced).
Hence, it acts as an oxidizing agent
, not reducing.
\(\Rightarrow\) Incorrect
Statement-II:
{\(\mathrm{KMnO_4}\) reduces nitrite, oxalate and iodide ions.}

\(\mathrm{KMnO_4}\) oxidizes
nitrite \((\mathrm{NO_2^-})\), oxalate \((\mathrm{C_2O_4^{2-}})\), and iodide \((\mathrm{I^-})\).
It does not reduce them.
\(\Rightarrow\) Incorrect

Final Conclusion:
Both Statement-I and Statement-II are incorrect
.
