What is the difference between a zeotrope and an azeotropes?
Azeotropic Mixtures:
The binary mixture(liquid mixtures) having the same composition in liquid and vapor phase and boil at constant temperature are called Azeotropic Mixtures.
In such cases, it is not possible to separate the components by fractional distillation.

In distillation, separation is achieved by exploiting the boiling point difference between components. Azeotropes are constant boiling mixtures, i’e they will boil at a constant temperature. For example, the ethanol-water mixture of composition 95.63% ethanol and 4.37% water forms the azeotrope and their onwards boils at a constant temperature of 78.2 °C. So it is impossible to get a concentration higher than 95.63% ethanol by normal distillation. To overcome this we can use azeotropic distillation.
