What is acid rain?

Rain water having a pH of less than 5.6 is called acid rain.

Acid rain: The rain containing the acidic oxides such as oxides of carbon, nitrogen and sulphur.

Acid rain is infact cocktail of mainly H₂SO₄ and HNO₃ where the ratio of these two may vary depending upon the relative quantities of oxies of sulphur and nitrogen emitted.

Every source of energy that we use-be it coal fuel, wood or petroleum products has sulphur and nitrogen. These two elements, when burnt in atmospheric oxygen are converted into their respective oxides which are highly soluble in water.

Factories and vesicles excrete sulphuric, nitrogen oxide. These remain the environment for long time. By chemical and photochemical reactions, sulphuric acid and nitric acid are formed and combines with water vapors in the environment. This is called ‘Acid Rain’.

Factories and vehicles excrete sulphuric, Nitrogen oxides. These remain the environment for longtime. By chemical and photo chemical reac tions, sulphuric acid and nitric acid are formed and combines with water vapors in the environment, This is called ‘Acid Rain’.

When pH of rain water is less than 5.6, it is called acid rain.

Acid rain is a form of precipitation that contains acidic components, such as sulfuric acid or nitric acid. It damages trees, crops and harms marine animals (coral reefs) and induces corrosion.

Rain mixed with sulphuric acid is called acid rain

Acid rain is rain with a pH of less than 5 due to dissolution of sulphur dioxide, nitrogen oxides and hydrochloric acid in it.
