colors in chemistryUsing Paper Chromatography to Understand Polarity

by Chandra Goetsch, Rachel Zuercher, Ruth Herradora, and Burnne Yew

It’s difficult for students to understand some chemistry concepts, such as polarity, without being able to see a molecule. This module visually shows students the difference between polar and nonpolar substances. It helps students understand separation chemistry and gives them a background to understanding other chromatography techniques.

Students learn: 1) How chromatography helps scientists test the components of different mixtures, 2) How solubility of polar and nonpolar substances differ depending on the solvent, and 3) How to collect data during an experiment.
