Question
Give one equation to show the following property of sulphuric acid:
As a non-volatile acid
Advertisements
Solution
It has a high boiling point, so it is used to prepare volatile acids such as HCl, HNO3 and acetic acid from their salts.
\[\ce{NaCl + H2SO4 -> NaHSO4 + HCl}\]
\[\ce{NaNO3 + H2SO4 -> NaHSO4 + HNO3}\]
\[\ce{CH3COONa + H2SO4 -> NaHSO4 + CH3COOH}\]
