Solution
Concentrated sulphuric acid has a high boiling point (356°C). So, it is considered to be non-volatile. Hence, it is used for preparing volatile acids like hydrochloric acid and nitric acids from their salts by double decomposition.
\[\ce{NaCl + H2SO4 -> NaHSO4 + HCl}\]
\[\ce{NaNO3 + H2SO4 -> NaHSO4 + HNO3}\]
