    Answer. SO 2 is a colourless and pungent smelling gas. It can be detected with the help of potassium permanganate solution. When SO 2 is passed through an acidified potassium permanganate solution, it decolonizes the solution as it reduces MnO 4- ions to Mn 2+ ions. 5SO 2 + 2MnO 4- + 2H 2 O → 5SO 42- + 4H + + 2Mn 2+.
