Azeotropes are the binary mixtures of solution that have the same composition in liquid and vapour phase and that have constant boiling points throughout distillation.

A minimum-boiling azeotrope is formed by solution showing a large positive deviation from Raoult's law at specific composition.

Example: An ethanol-water mixture containing approximately 95% ethanol by volume.
