- Acid rain occurs when the pollutants that come from immobile sources such as smokestacks, power plants, and mobile sources such as cars rise up into the clouds and fall back to earth as contaminated rainfall. The rain becomes acidic because of gases which dissolve in the rain water to form various acids. Rain is naturally slightly acidic because of the carbon dioxide dissolved in it. Acidic water contains an excess of hydrogen ions. Absolutely pure water contains equal numbers of acidic and basic ions (H+ and OH-). This gives rain a pH of around 5.0. Acid rain is formed by the reaction of rain water to a combination of various gases. Acid rain has some rather disastrous consequences on human, plant and animal life. Kindly find the attachments for more knowledge about the acid rain.
