उत्तर
- Oxidising agent: Concentrated sulphuric acid as an oxidising agent oxidises carbon to carbon dioxide.
\[\ce{\underset{Carbon}{C} + 2H2HO4 -> \underset{Carbon dioxide}{CO2} + 2SO2 + 2H2O}\] - Non-volatile acid: Concentrated sulphuric acid has a high boiling point (338°C) that is why it is said to be a non-volatile compound; therefore, it is used for preparing volatile acids like hydrochloric acids and nitric acids from their salts by double decomposition.
\[\ce{H2SO4 + NaCl -> NaHSO4 + HCl}\]
