Hrithik tested the nature of rainwater and found it to be acidic. a) Name any two acids present in acid rain. b) Name two air pollutants responsible for acid rain.
Answers
Answer:
a) 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.
b) Nitrogen dioxide and Sulphur dioxide are responsible for acid rain.
a: two acids present in acid rain are sulphuric acid and nitric acid
b: two air pollutants responsible for acid rain are Sulphur dioxide and nitrogen oxide
Nitric oxide (NO), which also contributes to the natural acidity of rainwater, is formed during lightning storms by the reaction of nitrogen and oxygen which in turn reacts with water to give nitric acid (HNO3).
sulfuric acid may be produced naturally from biological decay and volcanic activity , the combustion of sulfur-containing fossil fuels in power plants. When these fossil fuels are burned, the sulfur contained in them reacts with oxygen from the air to form sulfur dioxide which reacts with water to form sulphuric acid.
