Question

Acid rain occurs when sulfur dioxide and nitrogen oxides combine with water vapors in the atmosphere and fall as rain. Which of the following is not caused by acid rain?
  1. Decreased quality of air
  2. Reduced growth of forests
  3. Reduced pH of water bodies
  4. Destruction of marble buildings

Acid rain does not pollute air rather acid rain is caused due to the air pollution. The air pollutants consisting SO2 and NOx, they combine with the water vapour.

SO2+O2+H2OH2SO4

NO+H2OHNO2

NO2+H2OHNO3

Due to the formation of these acids, the rain is acidic.

Q2
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.

Read the passage and answer the following questions:
Acid rain is formed after the burning of fossil fuels releases compounds containing nitrogen and sulfur into the atmosphere. Sunlight and rain bring about chemical reactions that convert these compounds into nitric acid and sulfur dioxide, which combine with water droplets to form acid rain. Acid rain typically has a pH of approximately 5.5. "The higher acidity of soil and water affects many living organisms adversely. As the pH of lake water falls, fish become ill and die. Table 1 shows the effects of pH on the size of adult fish.

Mycorrhizal fungi, which form a mutualistic association with many plant roots, are particularly sensitive to the effects of acid rain. These fungi facilitate the
absorption of water and nutrients by the plants; in turn, the plants provide sugars and amino acids without which the fungi could not survive.
