what is chromatography? where it is used?
Answers
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.
