Question

Acid rain is known to contain some acids. Name these acids and where from they come in rain?

✓

Answer

The acids commonly present in acid rain are nitric acid, sulphuric acid and carbonic acid. Nitric acid is formed by oxidation of nitric oxide present in air to $\mathrm{NO}_2$ & $\mathrm{NO}_3$, which dissolve in water also present in air. Sulphuric acid is formed by the oxidation of $\mathrm{SO}_2$ result in air to $\mathrm{SO}_3$ followed by dissolution in water. $\mathrm{CO}_2$ present in the acid dissolves in water to give carbonic acid.
