“The formation of azeotropes due to deviations from Raoult's law was discussed in Section 1.3. An azeotrope is a mixture that, at a given pressure (the azeotropic pressure), boils at a constant temperature (the azeotropic temperature), and has the same composition (the azeotropic composition) in the equilibrium vapor and liquid phases. Homogeneous azeotropes are those that form⟳ one liquid phase at equilibrium with the vapor; heterogeneous azeotropes are those that form⟳ two liquid phases at equilibrium with each other and the vapor.”

“When a ternary azeotrope does exist⟳, the curves intersect at the same point⟳. The presence of a unitary azeotrope curve is not a prerequisite for the generation of a ternary azeotrope.”

“As the boiling point⟳ of HCl–H₂O azeotrope is lower than that of azeotrope (HNO₃–H₂O), hydrochloric acid can be eliminated efficiently by successive evaporations with nitric acid.”
