Which of the following is correct representation of reaction of acidified permanganate solution with sulphur dioxide?
- 2MnO4– + 5SO2 + 2H2O → 5SO42– + 2Mn2+ + 4H+
- MnO4– + SO2 + 2H2O → S + Mn2+ + 4H+
- 2MnO4– + 5SO2 + 2H2O → 4SO32– + S + 2Mn2+ + 4H+
- 3MnO4– + 2SO2 + 2H2O → 2S + 3Mn2+ + 4H+
Answer
(A) 2MnO 4 – + 5SO 2 + 2H 2 O → 5SO 4 2– + 2Mn 2+ + 4H +
