What is the main cause of formation of sulphuric and nitric acids in acid rain?
Answer and explanation
Correct answer: Reaction of sulphur dioxide and nitrogen oxides with atmospheric water
Burning coal, petroleum, and other fossil fuels releases sulphur dioxide and nitrogen oxides. In the atmosphere, these gases undergo oxidation and react with water droplets, producing sulphuric acid and nitric acid or related acidic substances. The acids are then carried to the ground with rain. Oxygen does not directly become salt, sodium chloride does not melt into acids, and limewater evaporation is unrelated; therefore A is correct.
