A homogeneous mixture contains two liquids. How are they separated ?

A homogeneous mixture of two liquids consists of miscible liquids that are evenly distributed and cannot be distinguished by the naked eye [1]. The standard method for separating such a mixture is distillation. Distillation exploits the differences in the boiling points of the constituent liquids. During this process, the mixture is heated; the liquid with the lower boiling point vaporizes first, is then cooled in a condenser, and collected as a separate liquid. While evaporation can separate a solid from a liquid in a homogeneous solution, it is not suitable for recovering both liquids in a liquid-liquid mixture. Filtration is ineffective for homogeneous mixtures because the particles are too small to be trapped by a filter and are not in a solid phase. Therefore, distillation is the most effective technique for separating two miscible liquids.
