SO 2 is considered as an air pollutant because

Options

  1. AIts concentration increases with temperature increase of atmosphere.
  2. BIt is used as an insecticide which is air pollutant
  3. CIt reacts with O 2 and H 2 O to produce acid rain
  4. DIt is a strong oxidant and oxidizes other components of atmosphere

Correct answer

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

Step-by-step solution

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.
