A binary liquid mixture of components A and B exhibits an azeotrope at a specific composition. Which of the following statements is ALWAYS true about this azeotropic mixture?
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.
