how HCl can be dried by passing through conc. sulfuric acid?

its a strong very strong dehydrating agent!

Yeah, agree with Shubham.

Concentrated Sulfuric acid absorbs water avidly and is an effective drying agent for
gases.

Because the hydration of sulfuric acid is thermodynamically favorable, sulfuric acid is an excellent dehydrating agent

It dehydrates HNO₃(nitric acid) too forming nitronium ion NO₂⁺

HNO₃ + 2H₂SO₄ â†’ NO₂⁺ + H₃O⁺ + 2HSO₄⁺

jus knew tht it was a strong dehydrating agent but was not sure abt the perfect reasons. thnks khyati!
