प्रश्न
Give two balanced reactions of the type to show the following property of sulphuric acid:
Non-volatile nature
Advertisements
उत्तर
Concentrated sulphuric acid has a high boiling point (356°C), so it is considered to be non-volatile. Therefore, it is used for preparing volatile acids like hydrochloric acid and nitric acid from their salts by a double decomposition reaction.
\[\ce{NaCl + H2SO4 -> NaHSO4 + HCl}\]
\[\ce{KCl + H2SO4 -> KHSO4 + HCl}\]
\[\ce{NaNO3 + H2SO4 -> NaHSO4 + HNO3}\]
