Question

what is mean by chromatography ? i want just one paragraph

Answer 1

Some materials appear homogenous, but are actually a combination of substances. For example, green plants contain a mixture of different pigments. In addition, the black ink in the pens that are used in this experiment is a mixture of different colored materials. In many instances, we can separate these materials by dissolving them in an appropriate liquid and allowing them to move through an absorbent matrix, like paper. Chromatography is a method used by scientists for separating organic and inorganic compounds so that they can be analyzed and studied
