One of the revision questions (help would be appreciated):
H2O(l) + HCl(g) ⇌ H3O+(aq) + Cl-(aq)
Explain why HCl is shown in the gas state rather than aqueous.

Hydrogen monochloride is not an acid in gaseous state, only when added to water does it ionise and form the characteristic H3O+.
(Hydronium ion) and is thus known as hydrochloric acid.

This supports the Bronsted Lowry theory for acids and bases, when HCl(g) is added to water, water accepts H+ to form H3O+, as a proton acceptor - water acts as a base and as HCl(g) donates the H+ it is an acid.
