The ‘normal’ rain is mildly acidic showing a pH value of around 6. This mild acidity is due to dissolution of CO2, that forms carbonic acid.

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides
are released into the air. These substances can rise very high into the atmosphere, where they mix and react
with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain. Sulfur dioxide and
nitrogen oxides dissolve very easily in water and can be carried very far by the wind
