Answer:
When the pH falls below 5.6, the rain is regarded as acid rain.
Explanation:
The presence of excessive acids in water is referred to as acid rain. The acids mainly present in acid rain are sulphuric acid, nitric acid, sulphurous acid, nitrous acid, hydrochloric acid, carbonic acid etc.
These are formed in the atmosphere by the dissolution of gases like SO₂, NO₂, Cl₂ etc. released by automobiles and various industries in the moisture present in the air. These acids slowly fall on the earth as constituents of rain or snow.
