Simple distillation is used for homogeneous mixtures, particularly a solution of a solid dissolved in a liquid or two liquids with very different boiling points.Example of mixture used:Saltwater (tubig-alat) — salt is dissolved in water.Alcohol and water — when the difference in boiling points is large.Why use simple distillation?It separates components based on boiling point — the liquid with the lower boiling point evaporates first, then is cooled and collected.
