2.people separate mixtures in order to ger a specific substance that they need.
the other thing people separate mixtures to remove the unrequired components.
To get pure substances.
3. chromatography: Involves solvent separation on a solid medium. distillation: Takes advantage of differences in boiling points.
4.separatory funnel, also known as a separation funnel, separating funnel, or colloquially sep funnel, is a piece of laboratory glassware used in liquid-liquid extractions to separate (partition) the components of a mixture into two immiscible solvent phases of different densities.[1] Typically, one of the phases will be aqueous, and the other a lipophilic organic solvent such as ether, MTBE, dichloromethane, chloroform, or ethyl acetate. All of these solvents form a clear delineation between the two liquids.[2] The more dense liquid, typically the aqueous phase unless the organic phase is halogenated, sinks and can be drained out through a valve away from the less dense liquid, which remains in the separatory funnel.
Answer:
mixtures
Most of the materials around us are mixtures . If two or more substances are mixed together in any proportion do not undergo any chemical change but retain their own properties the resulting mass is called a mixture
