Study Notes

Paper Chromatography

Technique for separating and analyzing mixtures of different colors.
Uses two phases: stationary and mobile.
Stationary Phase: The paper, which remains fixed.
Mobile Phase: The solvent, which travels up the paper through capillary action.
Different colors travel at varying rates due to their unique attraction to the paper (stationary phase) and their solubility in the solvent (mobile phase).
Components with a higher affinity for the paper (stationary phase) travel slower.
Components highly soluble in the solvent (mobile phase) move faster and further up the paper.
