This Paper Chromatography lesson plan also includes:
Students use this design the illustrate how ink can be separated into its component chemicals using paper chromatography. They use five unknown samples of ink on pre-labeled chromatography strips are provided to students. Students use these strips and water as a solvent to separate each ink into its component colors by paper chromatography. They use their results and knowledge of the process to design an experiment which identifies an unknown mixture of inks.
