Q. 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) Statement-I is incorrect but Statement-II is correct
B) Both Statement-I and Statement-II are correct
C) Both Statement-I and Statement-II are incorrect
D) Statement-I is correct but Statement-II is incorrect
Explanation
[Solution from source] In both reactions MnO₂ (Mn +4) acts as the oxidant, converting the halide to Cl₂ or I₂ and itself becoming Mn²⁺. Manganese is reduced in both cases, so Statement I is false and Statement II is true. Answer (1).
