Paper Chromatography: Separation of Ink Pigments—ChemTopic™ Lab Activity

firewatch

Many inks are actually mixtures made up of several basic pigments with a different color, structure and physical and chemical properties. With the Paper Chromatography: Separation of Ink Pigments—ChemTopic™ Lab Activity, determine whether ink samples are pure substances or mixtures as they are separated using paper chromatography.

Concepts

  • Mixture vs. Pure Substance
  • Chromatography
  • Separation of a Mixture
  • Adsorption
