Why sulphuric acid is used for the preparation of volatile acids such as HCl, HNO3, and acetic acid?
Asked by Topperlearning User | 21 Apr, 2016, 10:26: AM
answered-by-expert Expert Answer

Sulphuric acid has a high boiling point. Due to it’s non-volatile nature, 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
