NEET BIOLOGY

Detailed explanation-1: -In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.

Detailed explanation-2: -Acid rain is caused by the release of sulfur dioxide and nitrogen oxides into the atmosphere, where they react with water, oxygen, and other chemicals to become sulfuric and nitric acid respectively. The pH of acid-impacted rain is generally below 4.5 on the pH scale.

Detailed explanation-3: -Acid rain can be caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released to the air. Theses substances can rise into the atmosphere, where they mix and react with oxygen, water and other chemicals to form acid pollutants, therefor creating acid rain.

Detailed explanation-4: -Because carbonic acid is a relatively weak acid, the ability of carbon dioxide alone to generate true “acid rain” is very limited. Acid rain is caused by industrial emissions of sulfur dioxide and nitrogen oxides (which form much stronger acids when equilibrated in rainwater).
