Question

Explain phenomenon of acid rain.

Answer 1

The rain having an elevated concentration of sulphuric acid is known as acid rain. When SO₂ reacts with water in the atmosphere, it forms sulphuric acid, which washes the soil by rain. It is a disastrous effect of air pollution. It severely affects the growth of plants and animals and destroys buildings by eroding their stone and brickwork (e.g., Taj Mahal).
