Detailed Solution

Sulphuric acid is formed when sulphur dioxide (SO₂) combines with water (H₂O) in the atmosphere. Similarly, nitric acid is formed when nitrogen dioxide (NO₂) combines with water.

Acid rain is a type of precipitation that occurs when sulphur dioxide and nitrogen oxides are released into the atmosphere through human activities such as burning fossil fuels and then reacting with water, oxygen, and other chemicals to form sulphuric and nitric acids. These acids lower the pH of rainwater, making it more acidic than normal rain.

Acid rain can have harmful effects on the environment, including damaging forests, lakes, rivers, and soil, and also affecting the health of humans and wildlife.
