Question

Name the major constituent of Acid rain.

• A. $\left(S{O}_2\right)$
• B. $\left(C{O}_2\right)$
• C. $\left(CO\right)$
• D. $\left(O_2\right)$

Answer 1

The correct option is A

$\left(S{O}_2\right)$

The most important gas which leads to acid rain is Sulphur dioxide$\left(S{O}_2\right)$. Emission of Nitrogen oxides$\left(NO\right)$ also plays a vital role. Nitrogen oxides can also be produced naturally by lightning strikes, and Sulphur dioxide is produced by volcanic eruptions.
