उत्तर
The property used to prepare HCl and HNO3 from H2SO4 is that sulphuric acid is non-volatile acid. So when treated with salts of more volatile acids and heated, concentrated sulphuric acid displaces the more volatile acids.
\[\ce{KCl + H2SO4 ->[<200°C] KHSO4 + HCl}\]
\[\ce{KNO3 + H2SO4 ->[<200°C] KHSO4 + HNO3}\]
