MediumWhat is meant by the term "chromatography"?
(N/A) Chromatography is a collective term used for a family of laboratory techniques for the separation of mixtures.
The term is derived from Greek words 'chroma' meaning 'colour' and 'graphein' meaning 'to write'.
Chromatographic techniques are based on the principle that different components of a mixture are adsorbed to different extents on a stationary phase.
There are several chromatographic techniques such as paper chromatography,column chromatography,gas chromatography,etc.

View SolutionGiven below are two statements:
Statement $I$: Vapours of the liquid with higher boiling point condense before vapours of the liquid with lower boiling points in fractional distillation.
Statement $II$: The vapours rising up in the fractionating column become richer in high boiling component of the mixture.
