Question

The two strong acids present in the acid rain are:
A. $HN{O_2}$ and $HN{O_3}$
B. ${H_2}S{O_4}$ and $HN{O_3}$
C. ${H_2}S{O_3}$ and ${H_2}S{O_4}$
D. ${H_2}C{O_3}$ and $HCl$

Answer 1

Hint: First we need to understand what acid rain is. Acid Rain is determined as the condensation of acid in the formation of rain droplets. Now, we need to focus on the main components of the acid rain.

Complete step by step answer:
When the meteorological pollutants such as the oxides of nitrogen and sulfur react with this rainwater and come down with the rain, acid rain is formed. The leading cause of acid rain is sulfur and nitrogen particles, which get mixed with rain's wet components.
The two strong acids that are present in the acid rain are sulfur dioxide and nitrogen oxide. These two gases further react with the rainwater and the oxygen present in the atmosphere.
The reaction when these two gases react with water in the atmosphere and oxygen gives sulfuric acid and nitric acid as the products of the reaction.
In the first reaction, we will show the reaction when sulfur dioxide reacts with water and oxygen. Then, sulfuric acid is formed as the by-product of the reaction.
$2S{O_2} + {O_2} + 2{H_2}O \to 2{H_2}S{O_4}$
In the next reaction, we will show the reaction when nitrogen oxide dioxide reacts with water and oxygen. Then, nitric acid is formed as the by-product of the reaction.
$4N{O_2} + {O_2} + 2{H_2}O \to 4HN{O_3}$
Thus, the main agents causing acid rain are sulfuric acid and nitric acid.
So, the answer will be option D.

Note:
-Acidification increases acidity in the soil that further destroys farms, forests and crops.
-Acid rain affects the life of the aquatic animals.
-When the air or water around us gets contaminated then it might be a serious threat to human life.
-By preventing the emission of sulphides and nitrides in the atmosphere we can control the formation of acid rain.
