Given below are two statements: Statement-I : Heating NaCl with concentrated H₂SO₄ and MnO₂ results in oxidation of Mn. Statement-II : Heating NaI with concentrated H₂SO₄ and MnO₂ results in reduction of Mn. In light of the above statements, choose the most appropriate answer from the options given below:
A
Both Statement-I and Statement-II are correct.
B
Both Statement-I and Statement-II are correct but Statement-II is NOT the correct explanation of Statement-I.
C
Statement-I is correct but Statement-II is incorrect.
D
Statement-I is incorrect but Statement-II is correct.
Explanation
Heating NaCl with concentrated H₂SO₄ and MnO₂ reduces Mn, not oxidises it. S-(I) 4NaCl + MnO₂ + 4H₂SO₄ → MnCl₂ + 4NaHSO₄ + 2H₂O + Cl₂ i.e. statement is wrong. S-(II) 2NaI + MnO₂ + 4H₂SO₄ → I₂ (↑) + MnSO₄ + Na₂SO₄ + 2H₂O Heating NaI with conc. H₂SO₄ and MnO₂ reduce Mn. statement is correct.
