Describe paper chromatography.
- Place solute on paper on base line drawn in pencil.
- Place paper in solvent with solvent level below base line.
- Compare the components of the solution tested with known substances and their respective chromatographs.
- Chromatography works by testing the solubilty of the different subtances that make up the solution, thus by comparing the distances (which relate to the solubility of the substance) they travel up the paper with the known substances we can know.
If substances are colourless locating agents that mark them may be used to facilitate testing.
