Curated OER
Chromatographic Separation of Methylene Blue and Sodium Fluorescein
Students determine the best solvent system for separating a methylene blue/sodium fluorescein mixture by thin layer chromatography. They conduct an initial TLC separation using ethanol and a different solvent mixture and analyze the data...
Curated OER
Chromotography
In this chromatography activity, students are given markers, filter paper and a solvent to separate the pigments found in each marker. Students create a chromatogram for each marker.
Curated OER
Plant Pigments
Students investigate the components of chlorophyll. They use paper chromatography to separate the many pigments of chlorophyll from one another.
Curated OER
Chromatography of photosynthetic pigments
Students explore the technique of chromatography to separate compounds in a mixture. In small groups, they separate by paper chromatography and identify the major and accessory photosynthetic pigments.....................................

How Do I Get a Pure Sample of the Molecules I Make?
Learners initially engage in online research and consult print materials to identify a compound to produce. Once a selection has been made, individually, students conduct lab experiments to isolate substances. The end product is a...
