Answer Details
The principle of column chromatography is based on the ability of the constituents to move at different speeds in the column. In column chromatography, a mixture is passed through a column containing a stationary phase (e.g. silica gel) and a mobile phase (e.g. solvent). Different constituents of the mixture have different affinities for the stationary and mobile phases, and thus move at different speeds through the column. This allows them to be separated based on their different physical and chemical properties.
