chemical or physical separation methods used

the chemical and physical separation methods that are used

A: Extraction, distillation, recrystallization and chromatography are different chemical methods of separation. Extraction is useful for separating compounds with different polarities, and distillation is commonly used to purify liquids. Recrystallization is used to purify solids, and chromatography is used to separate compounds and mixtures.

Separation Techniques Classification of Matter

A separation process or technique is a method that converts a mixture or solution of chemical substances into two or more distinct product mixtures.At least one of results of the separation is enriched in one or more of the source mixture’s constituents. In some cases, a separation may fully divide the mixture into pure constituents.
