Recognition and Classification of Mixtures
Immerse your chemistry class in solutions! They melt and compare the mixtures that make up margarine, separate black ink into its component colors, distill ocean saltwater, and practice chromatography with plant pigments. There are eight...

Paper Chromatography K-12 Experiment
Students study chromatography and how they can distinguish between the different pigments in a color. In this chromatography lesson students separate a mixture of dyes in soluble ink then record the colors they see.
Curated OER
Chromatography
Students 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.

The Conceptual Theory of Chromatography
Students conduct a lab to determine the best way to separate a variety of mixtures choosing between paper, thin layer and column chromatography. They use chromatography techniques to identify unknown substances and submit a lab report on...
Curated OER
Ink Analysis and Thin Layer Chromatography
Students explain the process of TLC. They identify at least three components of ink. They analyze data and make conclusions based on laboratory observations.
Curated OER
Introducing Chromatography
Students investigate chromatography. In this chromatography lesson, students investigate a lab set up for chromatography.
Curated OER
Paper Chromatography
Students participate in an experiment determining how to separate a mixture of dyes in water-soluble ink.
Curated OER
Introduction to Gas Chromatography
Students analyze gas chromatograms and suggest various applications for gas chromatography.
