Answer 1

In chemistry, both elements and compounds are pure substances. An aqueous solution of hydrogen chloride is called hydrochloric acid, and it is also usually given the same formula (HCl) as that of pure hydrogen .

Answer 2

Hydrochloric acid is a mixture. Although we use HCl as the formula for hydrochloric acid, HCl is, in fact, the formula of hydrogen chloride, which is a compound. Hydrogen chloride is a gas which readily reacts with water.

HCl + H2O ———-> H3O^+(aq) and Cl^-(aq)

Hydrochloric acid is a mixture of these ions

H2O and H3O^+(aq) and Cl^-(aq)

There are many different concentrations of hydrochloric acid - it must be a mixture.
