Separation of Unknowns in a Liquid
Learners identify chromatography as method of separating the components of a liquid. Students discover that dyes are composed of more than one component in achieving a particular color in these lessons on paper chromatography.
Curated OER
Separation of Unknowns in a Liquid
Learners identify the different components of a given sample using chromatography. In this chemistry lesson plan, students compare paper and column chromatography. They collect data and construct data tables.

Major Organic Acids in Fruits
Young scholars investigate the organic acids present in a variety of juices. In this organic acids lesson plan, students read about the effects of organic acids in juices. They use paper chromatography to separate out the acids present...
Curated OER
See Spot Run
Students identify several properties of water as a universal substance, describe the composition of several complex color mixtures and separate the components of dye using chromatographic technique.
Curated OER
Column Chromatography
Students research the mechanics of liquid chromatography. In this technology instructional activity, students calculate the concentration of unknown samples. They write a report about their research and lab results.
Curated OER
Chromatography of Foods
High schoolers complete a counter top chemistry experiment on the chromatography of foods. The experiment is based upon the relative attraction of the components of the mixture for the mobile phase (water) and the stationery phase (paper).
Curated OER
Chromatography
Learners conduct various experiments on chromatography. In this chemistry lesson, students distinguish among the different types of chromatography methods. They explain how the stationary and mobile phase interact with each other.
Curated OER
Introduction to Gas Chromatography
Students analyze gas chromatograms and suggest various applications for gas chromatography.
