Solution:
Paper chromatography is an analytical method that is
used to separate coloured chemicals or substances,
especially pigments. This can also be used in secondary
or primary colours in ink experiments. Leaf pigments of
any green plants can be separated by using paper
chromatography. A chromatographic separation of the leaf
pigments shows that the colour we see in leaves is due to
a single pigment but due to four pigments: chlorophyll a
(bright or blue green in the chromatogram), chlorophyll b
(yellow green), xanthophylls (yellow) and carotenoids
(yellow to yellow orange).
