MCQ
The most efficient agent for the absorption of $S{O_3}$ is
- A$80\% \;{H_2}S{O_4}$
- ✓$98\% \;{H_2}S{O_4}$
- C$50\% \;{H_2}S{O_4}$
- D$20\% \;{H_2}{S_2}{O_7}$
✓
Answer
Correct option: B.
$98\% \;{H_2}S{O_4}$
b
(b) $98\%$ ${H_2}S{O_4}$ is used for absorbing dense fog of acid which is formed by dissolving $S{O_3}$in water. Hence $98\%$ ${H_2}S{O_4}$is the most efficient agent for the absorption of $S{O_3}$.
(b) $98\%$ ${H_2}S{O_4}$ is used for absorbing dense fog of acid which is formed by dissolving $S{O_3}$in water. Hence $98\%$ ${H_2}S{O_4}$is the most efficient agent for the absorption of $S{O_3}$.
