Question

$S{O}_2$ is known to produce acid rain.

• A. True
• B. False

Answer 1

The correct option is A True

$S{O}_2$ produces acid rain. It reacts with atmospheric oxygen to produce $S{O}_3$. This sulphur trioxide reacts with water to produce Sulphuric Acid. Thus acid rain is produced.

$2S{O}_2$ $+$ $O_2$ $=$ $2S{O}_3$

$S{O}_3$ $+$ $H_{2}O$ $=$ $H_{2}S{O}_4$
