Aqueous sulphite reacts with dilute sulphuric acid to form \(X(g)\). The liberated \(X(g)\) is passed into acidified \(\mathrm{KMnO}_4\) solution. What is the oxidation state of \(\mathrm{Mn}\) in the product formed?
- A 6
- B 4
- C 2
- D 3
Answer & Solution
Correct Answer
(C) 2
Step-by-step Solution
Detailed explanation
Aqueous sulphite when reacts with sulphuric acid, it gives \(\mathrm{SO}_2(g)\) which when react (passed) with acidified \(\mathrm{KMnO}_4\) gives \(\mathrm{Mn}^{2+}\) ions as follows: (i)…
