Paper chromatography

Cards (8)

  • 1 Draw line near bottom of filter paper
  • 2 Add ink to the line and put the paper in a beaker of solvent (water)
  • 3 make sure the ink isn’t touching the solvent so it doesn’t dissolve
  • 4 put a lid on the container to stop the solvent evaporating
  • 5 solvent seeps up the paper, carrying the ink with it
  • 6 the different dye in the ink will move up the paper at a different rate so the dyes will separate out
  • 7 if any dyes are insoluble they’ll stay on the baseline
  • 8 when the solvent is nearly at the top of the paper, take the paper out and leave it to dry
