Verified by Experts

The correct answer is:

It reacts with O 2 and H 2 O to produce acid rain

SO 2 is considered as air pollutant because it reacts with O 2 and H 2 O to produce acid rain. Oxides from nitrogen and sulphur, released into the atmosphere from thermal power plants, industries and automobiles are the main sources of acid rain. These oxides on oxidation followed by hydrolysis give sulphuric acid and nitric acid that get dissolved in rain water and are responsible for the acidity of rain.
