Chromatography:

  • Inks, paints and foods tend to contain mixtures of coloured compounds.
  • Chromatography can be used to find out what the coloured compounds are.

Paper Chromatography:

  • Works because some compounds dissolve better in a solvent than others.
  • when a solvent moves along a ***** of paper it carries different substances in that mixture at different speeds, so they are separated.
  • The solvent is called the mobile phase.
  • The paper contains the stationary phase,
