Because when the azeotrope is boiled, the vapor produced has proportionate constituents as the original mixture.

What are azeotropic?

Azeotropic obey Raoult's law at all temperature.

If a binary mixture having relative volatility close to unity then we say that mixture is azeotropic at that temperature and pressure.

If mixture is azeotropic then xi = yi.


Xi = mole fraction of component i in liquid phase.

Yi = mole fraction of component i in the vapor phase.

Azeotropic solutions are constant boiling mixtures which cannot be separated by simple distillation, because the vapours formed will be consisting of same composition as that of the unboiled solution.

Azeotropic means the same composition of liquid and vapour phase.
