Final answer:
Paper and thin layer chromatography are commonly used for separation of mixtures. They are used in forensic science and chemistry labs for various purposes.
Step-by-step explanation:
Paper and thin layer chromatography are often used for separation of mixtures. In paper chromatography, a mixture is adsorbed on a porous paper and separated by ascending through the capillaries in the paper. Thin layer chromatography involves the separation of mixtures on a thin layer of adsorbent material, such as silica gel or alumina, coated on a glass or plastic plate.
Both paper and thin layer chromatography are widely used in various fields. They are commonly used in forensic science for analyzing ink or distinguishing between different proteins in fingerprinting techniques. They are also used in chemistry labs to separate and identify the components of a mixture.
