Question

Hritik tested rainwater and found a pH of 5-6 due to presence of H+ ions formed by reaction of rainwater with carbon dioxide. When pH of the rainwater drops below 5-6, then it is called acid rain. Oxides of nitrogen and sulphur are acidic in nature. Burning of fossil fuels such as coal and oil in power stations and furnace produce oxides of nitrogen and sulphur. He told all of his classmates living nearby to use bicycle instead of school bus so as to reduce air pollution and prevent acid rain.
(a) Which acid is formed by sulphur dioxide in presence of air?
(b) Which acid is formed by nitrogen dioxide in presence of air?
(c) Why is acid rain harmful for agriculture, trees and plants?
(d) How can we prevent from acid rain?
(e) What values are possessed by Hiritik?

Answer 1

Answer:

1) sulphuric acid

2)Nitric acid

3) Because it damages the plant life, and mqkes it out of its nature and atops the growth.

4) He is a science lober.

thanks??

Answer 2

Sulphuric acid

Nitric acid

Toxic substances

Renewable energy

Environmentally conscious

Explanation:

(a) When sulfur dioxide combines with water and air, it forms sulfuric acid, which is the main component of acid rain

(b) Nitric acid is formed by nitrogen dioxide in presence of air.

(c) Acid rain causes the release of toxic substances such as aluminium into the soil. So it is harmful for plants and trees.

(d) A great way to reduce acid rain is to produce energy without using fossil fuels. Instead, people can use renewable energy sources, such as solar and wind power.

(e) Hritik asked all of his classmates living nearby to use bicycle instead of school bus, so as to reduce air pollution and prevent acid rain. He is environmentally conscious and also a physically active person.
