Current Question (ID: 17840)

Question:

$\text{Acid rain is due to an increase in the atmospheric concentration of:}$

Options:

1. $\text{Ozone, and dust}$
2. $\text{CO}_2, \text{ and CO}$
3. $\text{SO}_3, \text{ and CO}$
4. $\text{SO}_2, \text{ and NO}_2$

Solution:

$\text{HINT: Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH).}$ $\text{Explanation:}$ $\text{Acid rain is caused by large scale emission of nitrogen oxides (NOx), sulphur oxides (SOx), volatile organic carbon and HCl from thermal power plants, industries and automobiles.}$ $\text{Oxides of nitrogen and sulphur combine with water and oxygen and form nitric acid and sulphuric acid, respectively. Thus, option 4 is correct.}$
