MCQ
The most efficient agent for the absorption of $S{O_3}$ is
- ✓$98\%\,\, {H_2}S{O_4}$
- B$80\%\,\, {H_2}S{O_4}$
- C$20\% $ $oleum$
- D$90\%\,\, {H_2}S{O_4}$
✓
Answer
Correct option: A.
$98\%\,\, {H_2}S{O_4}$
a
(a) $\mathop {{H_2}S{O_4}}\limits_{{\rm{98\% }}} + S{O_3}\,\, \to \,\,\mathop {\mathop {{H_2}{S_2}{O_7}}\limits_{{\rm{Oleum}}} }\limits_{({\rm{Fuming}}\,{H_2}S{O_4})} $
(a) $\mathop {{H_2}S{O_4}}\limits_{{\rm{98\% }}} + S{O_3}\,\, \to \,\,\mathop {\mathop {{H_2}{S_2}{O_7}}\limits_{{\rm{Oleum}}} }\limits_{({\rm{Fuming}}\,{H_2}S{O_4})} $
