Aug 10, 2020 Chromatography. Chromatography is the separation of a mixture by passing it in solution or suspension or as a vapor as in gas chromatography through a medium in which the components move at different rates. Thin-layer chromatography is a special type of chromatography used for separating and identifying mixtures that are or can be colored, especially pigments.

The separation technique that involves heating a solution until the liquid changes into a gaseous state, leaving behind a solid is known as answer choices evaporation
Even though there are no chemical changes to the mixture, some alteration is observed in physical characteristics such as melting point and boiling point. The products separated can be different in chemical properties or some of the physical properties like size, crystal modification etc. Separation Techniques
PHYSICAL SEPARATION TECHNIQUES Introduction When two or more substances, that do not react chemically, are blended together, the result is a mixture in which each component retains its individual identity and properties. The separation of the components of a mixture is a problem frequently encountered in chemistry.
Separating funnel Magnetic separation Precipitation Lets discuss some of the separation techniques. Using a separating funnel A separating funnel is used for the separation of components of a mixture between two immiscible liquid phases. One phase is the aqueous phase and the other phase is an organic solvent. This separation is based on ...

IV. Chromatography-Chromatography is a family of analytical chemistry techniques for the separation of mixtures. It involves passing the sample, a mixture which contains the analyte, in the mobile phase , often in a stream of solvent, through the stationary phase. The stationary phase retards the passage of the components of the sample.
