(a) What is chromatography ? For which type of mixture is it used ?
(b) What are the advantages of chromatography ?
(c) Give two applications of chromatography.
(a) This is one of the latest techniques to separate the coloured components of a mixture when all the
components are very similar in their properties. Example: Components of ink are separated by this
method. Ink is a mixture of different dyes, which are separated by chromatography because some of
the dyes are less soluble and some are more soluble in a solvent.
(b)
1. A very small quantity of the substance can be separated.
2. Components with very similar physical and chemical properties can be separated.
3. It identi es the different constitutes of a mixture.
4. It also helps in quantitive estimation of components of a mixture.
(c) Chromatography applications :1) Growing its importance in drug development
2)In Chemical industry, Chromatography is applied in testing water samples and also checks air quality.
