Sulfur dioxide (SO2) and Nitrogen (NOx)

Detailed explanation-1: -Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground.
Detailed explanation-2: -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.
Detailed explanation-3: -Acid rain is formed high up in the atmosphere when SO2 and NO2 combine with water and sunlight. When this reaction forms acid it falls to the ground in the form of acid rain or snow.
Detailed explanation-4: -Causes of acid rain The biggest sources are coal-burning power plants, factories, and automobiles. When humans burn fossil fuels, sulfur dioxide (SO2) and nitrogen oxides (NOx) are released into the atmosphere.
Detailed explanation-5: -NO2 and other NOx interact with water, oxygen and other chemicals in the atmosphere to form acid rain. Acid rain harms sensitive ecosystems such as lakes and forests.
