Question

State in the above reactions a reason for the formation of the respective acids from conc. H2SO4.

July 30, 2024

Answer

As H₂SO₄ is a less volatile acid and displaces the more volatile acid on heating with the salt, hence the respective acids are formed.

AB [salt I] + HX [acid I] ⟶ AX [salt II] + HB [acid II]
