Uncontaminated precipitation is naturally acidic. Water contains atmospheric gases as well as carbon dioxide, and when the carbon dioxide dissolves it forms carbonic acid, which makes the pH of normal rain about a 5.6 on the pH scale

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air.❤ Bhai I guess that was right answer

Acid rain is caused by a chemical reaction that begins when compound 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, is called acidic rain

The rain containing excess of acids is called acidic rain. Sulphur dioxide, nitrogen dioxide, carbon dioxide are released into the air as pollutants during the burning of various types of fuels used in factories, homes and automobiles.These gases,released in the atmosphere, are fairly soluble in water.
