Column chromatography separates the components of a mixture mainly on the basis of their

  1. Adifferent densities
  2. Bdifferential adsorption on the stationary phase
  3. Cdifferent colours
  4. Ddifferent molecular formulas only

Answer: B

Components that are adsorbed on the column adsorbent (alumina or silica gel) with different strengths are carried down at different rates by the eluent. This differential adsorption separates the components.
