• Non volatile acid

Answer 1

When HCl is prepared by the reaction of NaCl with H₂SO₄ the property of H₂SO₄ exhibited is non volatile acid.

Explanation:

Concentrated sulphuric acid is a non-volatile acid, so it displaces the more volatile hydrochloric acid from sodium chloride.

\[\ce{NaCl + H2SO4(conc{.}) -> NaHSO4 + HCl}\]
