Question

Gas which can be dried by passing through conc. $H_{2}S{O}_4$ is:

• A. $N_2$
• B. $O_2$
• C. $C{O}_2$
• D. all of the above

Answer 1

Answer: (D)

all of the above

Gases which are not basic can be dried by passing Conc. $H_{2}S{O}_4$ over it. It is because the Sulphuric acid has a great affinity for water and when it reacts with Compound containing water, it acts as a dehydrating agent. So all of the given gas can be dried by passing ions. $H_{2}S{O}_4$ through it:

Note: Ammonia can't be dried by using the same procedure because ammonia is a base and it will react with acid to given precipitate.
