Question

(c) Chromatography (d) Filtration
4. A special technique used nowadays for separation and identification of the constituents in a mixture
is chromatography.
The principle is based on difference in adsorption of constituents of a mixture by a surface of an
appropriate adsorbent material or solid medium (stationary) phase. The rate of adsorption of a
particular constituent depends upon its solubility in the solvent.
