How is the presence of SO2 detected | Class 12 Chemistry Chapter The p-Block Elements, The p-Block Elements NCERT Solutions

Question:

How is the presence of SO₂detected?

Answer:

SO₂is a colourless and pungent smelling gas.

It can be detected with the help of potassium permanganate solution. When SO₂is passed through an acidified potassium permanganate solution, it decolonizes the solution as it reduces MnO₄^- ions to Mn²⁺ ions

5SO₂ + 2MnO₄^-+ 2H₂O → 5SO₄^2- + 4H⁺ + 2Mn²⁺
