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