Question

Gases responsible for the acid rain are :
A.$NO,C{O_2}$
B.$N{O_2},S{O_2}$
C.$CO,C{O_2}$
D.$C{O_2},S{O_2}$

Answer 1

Hint:Acid rain is the condition when the precipitation occurring from the atmosphere is a bit acidic in nature. That is mainly due to the conversion of the water molecules into acid by the reaction of some non metallic oxides. They have very harmful effects over the various aspects of nature, both biotic and abiotic.

Complete step by step answer:
For the given question firstly we need to be aware with the term Acid Rain :
Acid rain: It is a kind of rain or any other kind of precipitation, that is generally acidic in nature, that means that the levels of hydrogen ions in the rain are elevated or are much greater than the normal rain. Therefore it has a low pH value in the pH scale which makes it little acidic in nature.
Acid rain also has very adverse and harmful effects on various biotic components of the surroundings such as the plants and aquatic animals. It even affects the abiotic components like infrastructure.
Processes involved in acid deposition
Acid rain is mainly caused by the emissions of the acidic oxides like the sulfur dioxide $S{O_2}$ and nitrogen oxide $N{O_2}$ . These oxides form acids when they react with the water molecules in the atmosphere. This makes the nature of the precipitation dilute acidic.

Therefore the right answer would be B, $N{O_2},S{O_2}$ .


Note:Acid rain is affecting the atmosphere way more than we see. Their main reason is the industries as they produce this harmful oxides. Taj Mahal got yellowish due to this acid rain, as the marble is corroded by the acidic nature of the rain. This is the primary reason for shifting the industries from Agra.
