Statement-I : Heating \( \text{NaCl} \) with concentrated \( \text{H}_2\text{SO}_4 \) and \( \text{MnO}_2 \) results in oxidation of \( \text{Mn} \). Statement-II : Heating \( \text{NaI} \) with concentrated \( \text{H}_2\text{SO}_4 \) and \( \text{MnO}_2 \) results in reduction of \( \text{Mn} \). In light of the above statements, choose the most appropriate answer from the options given below:

  1. Both Statement-I and Statement-II are correct.
  2. Both Statement-I and Statement-II are incorrect.
  3. Statement-I is correct but Statement-II is incorrect.
  4. Statement-I is incorrect but Statement-II is correct.

Correct answer · Option 2

Both Statement-I and Statement-II are incorrect.

Explanation

In both reactions, \( \text{MnO}_2 \) acts as an oxidizing agent and \( \text{Mn} \) undergoes reduction from \( +4 \) to \( +2 \), making both statements factually incorrect regarding oxidation of Mn.
