What two air pollutants are associated with the formation of acid rain?

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.

What are the main sources of sulfur dioxide SO2 and nitrogen oxides NOx in the atmosphere?

Sulfur dioxide comes from the burning of coal and oil. It is very smelly. The main sources of SO2 are power plants. Nitrogen dioxide comes from the burning of fossil fuels (like gasoline).

What are the components of acid rain?

Sulfuric acid, Nitric acid and carbonic acid are the major components of acid rain. The two strong acids present in the acid rain are nitrogen oxide and sulphur dioxide. These two gases react with water in the atmosphere and oxygen in the air to form sulphuric acid and nitric acid.

What is the acidity of acid rain?

Typical acid rain has a pH value of 4.0. A decrease in pH values from 5.0 to 4.0 means that the acidity is 10 times greater.

Why SO2 is an air pollutant?

Sulphur dioxide $S{O_2}$ is mainly produced by the incomplete combustion of fossil fuels in automobiles and factories. It is an air pollutant because it has a very harmful effect on the environment as it can create pollutants such as particulate matter, sulfate aerosols and most harmful of this acid rain.

What are some sources of sulfur air pollution?

These gases, especially SO2, are emitted by the burning of fossil fuels — coal, oil, and diesel — or other materials that contain sulfur. Sources include power plants, metals processing and smelting facilities, and vehicles.

How does sulfur dioxide cause acid rain equation?

Sulfur dioxide, like the oxides of carbon and nitrogen, reacts with water to form sulfuric acid (Equation 7-8). of H2SO4 causes the concentration of H+ ions to increase dramatically, and so the pH of the rainwater drops to harmful levels.

Which of the following pollutant causes acid rain Mcq?

It mostly occurs due to the presence of oxides of sulphur and nitrogen in the atmosphere. Nitrogen and sulphur oxides react with water vapour to form acids. Large amounts of sulphur and nitrogen oxides are emitted from power plants and large industries.
