Describe the principles of how paper chromatography works
Paper chromatography separates a mixture of solutions by their various solubilities. The less soluble components have a higher affinity to the stationary phase (the paper strip) while more soluble components have a higher affinity to the mobile phase, or solvent. They therefore travel up the strip at different speeds, causing them to separate out.
