80. An azeotrope is one that a.can be separated by distillation below critical solution temperature b.cannot be separated by distillation c.can be separated by distillation at critical solution temperature d.can be separated by distillation above critical solution temperature
The reason why azeotropes cannot be separated by simple distillation is because when azeotropes are boiled, the vapours have the same proportions of the constituents as the unboiled mixtures.
