Give one equation to show the following properties of sulphuric acid:
As a non-volatile acid
Advertisements
उत्तर
As a non-volatile acid:
It has a high boiling point, so it is used to prepare volatile acids such as HCl, HNO3 and acetic acid from their salts.
NaCl + H2SO4 → NaHSO4 + HCl
NaNO3 + H2SO4 → NaHSO4 + HNO3
CH3COONa + H2SO4 → NaHSO4 + CH3COOH
