Solution
The property exhibited by concentrated sulphuric acid when it is used to prepare hydrogen chloride gas from potassium chloride is non-volatile acid property.
Explanation:
The volatile acid HCl is removed from its salt solution through a reaction between H2SO4 and NaCl.
\[\ce{KCl + H2SO4 -> KHSO4 + HCl}\]
