Question

Explain the formation of acid rain due to oxides of sulphur

Answer 1

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

Both sulfur dioxide and nitrogen dioxide areacidic oxides and react with water to form acids. Sulfur dioxide reacts with water toform sulfurous acid. Substances in the upper atmosphere then catalyse the reaction between sulfurous acid and oxygen to form sulfuric acid.
