NEET 2026 Chemistry question
Given below are two statements : Statement-I : Heating NaCl with concentrated and results in oxidation of Mn. Statement-II : Heating NaI with concentrated and results in reduction of Mn. In light of the above statements, choose the most appropriate answer from the options given below.
Answer: (4)
Solution
With NaCl: 4NaCl + MnO_2 + 4H_2SO_4 \rightarrow MnCl_2 + 4NaHSO_4 + 2H_2O + Cl_2. Here (Mn +4) is reduced to (+2) and chloride is oxidised to . Mn is reduced, not oxidised, so
