Pure water is neutral and has a pH value of 7.0. If it is less than 7, then the water is acidic (has the traces of acids) and if it is more than 7, then it is basic. Due to rapid industrialisation and pollution, the water in the clouds is getting contaminated with the industrial vapours and condense in the form of acid droplens in them. As a result, the rain becomes acidic which is dangerous to the life. The crops will be affected due to this acid rain. The health of the people will also be affected.

Acid rain does not mean that it rains acid by itself. The fumes in the atmosphere get merged during the process of formation of cumulonimbus (i.e. the water bearing clouds). Also in a down pour, the fumes in the atmosphere get dissolved in water during its travel from sky to earth and form acids. So the pH of rain water when it reaches us becomes acidic.

Acid rain is rain or any other form of precipitation that is unusually acidic. It has harmful effects on plants, aquatic animals, and infrastructure. Acid rain is mostly caused by human emissions of sulfur and nitrogen compounds which react in the atmosphere to produce acids. In recent years, many governments have introduced laws to reduce these emissions.
