The composition of the vapor phase is identical to the composition of the liquid phase.
The boiling point of the azeotrope is the average of the boiling points of pure A and B.
The azeotrope can be separated into pure A and B by fractional distillation.
The azeotrope always shows a positive deviation from Raoult's Law.
