Conc. sulphuric acid is a _____ acid. (volatile/ not volatile)

Answer 1

• Conc. sulphuric acid is a _non-volatile_ acid.
• The boiling point of Sulphuric acid (${\mathbf{H}}_{\mathbf{2}}{\mathbf{SO}}_{\mathbf{4}}$) is very high around $338°$.
• Due to its high boiling point, it is considered as non-volatile acid.
• Sulphuric acid is used to prepare different volatile acids for example: Acetic acid (${\mathbf{CH}}_{\mathbf{3}}\mathbf{COOH}$), Hydrochloric acid ($\mathbf{HCl}$), Nitric acid (${\mathbf{HNO}}_{\mathbf{3}}$).
• Therefore, conc. Sulphuric acid is considered as non-volatile acid.
