Acid rain is a rain or any other form of precipitation that is unusually acidic. When fossil fuel such as coal and petroleum are burnt, they produce air-polluting gases such as sulphur dioxide and nitrogen dioxide. These gases react with the water vapour in the atmosphere and eventually form dilute solutions of sulphuric acid and nitric acid. These acids mix with rain water and come down in the form of acid rain. It can have harmful effects on human beings, vegetation, aquatic animals and buildings.

Acid rain is rain with a pH of less than 5 due to dissolution of sulphur dioxide, nitrogen oxides and hydrochloric acid in it. Acid rain is caused when the oxides of nitrogen and sulphur are precipitated from the rain water. These oxides are present in the upper atmosphere and when rain falls these oxides get dissolved in rain water and forms nitric acid and sulphuric acid thus makes it acidic.
