Ethanol and water form a homogeneous azeotrope. A heterogeneous azeotrope consists of immiscible liquids that separate into two phases. Chloroform and water form a heterogeneous azeotropic mixture.

What are azeotropic mixtures examples?

The most common example is the azeotrope between water and ethanol (grain alcohol). Water boils at 100 ºC and ethanol boils at 78.3 ºC. The mixture will boil at 78.2 ºC and have a composition of 95% ethanol and 5% water by volume. This is a binary azeotrope because it involves two components.

What mixture is azeotrope?

An azeotrope is a liquid mixture that has a constant boiling point and whose vapor has the same composition as the liquid.
