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: -Sulphur dioxide (SO2) and nitrogen oxides (NOx) are the two main pollutants that form acid rain. SO2 reacts with water in the air to form sulphurous acid (H2SO3), and then with oxygen to form sulphuric acid (H2SO4). NOx reacts with water to form nitric acid (HNO3).

Detailed explanation-3: -Nitric acid is a component of acid rain that forms when gaseous Nitrogen dioxide pollutant reacts with gaseous Oxygen and liquid water to form aqueous Nitric acid?

Detailed explanation-4: -Acid rain describes any form of precipitation that contains high levels of nitric and sulfuric acids. It can also occur in the form of snow, fog, and tiny bits of dry material that settle to Earth. Normal rain is slightly acidic, with a pH of 5.6, while acid rain generally has a pH between 4.2 and 4.4.
