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 SOdetected?

Answer:

SOis a colourless and pungent smelling gas.

 

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

5SO2    +     2MnO4-     +   2H2O    →   5SO42-    +   4H+   +  2Mn2+
