The October 2022 Xchange highlights just some of the contributions that have recently been published on ChemEd X. We hope you will take a moment to check in and see what you may have missed. 


Kool-aid, Cotton, and Intermolecular Forces

In honor of the 2022 theme for National Chemistry Week (NCW): "Fabulous Fibers: The Chemistry of Fabrics", we offer Tom Kuntzleman's post originally published in October 2016. Red dye #40 found in strawberry Kool-Aid and various cloth fibers can be used in a very simple experiment that can teach students about intermolecular forces. A video is included that describes the experiment and analysis of results. Celebrate National Chemistry Week 2022 the week of October 16–22, 2022!


Secret Messages with Elmer's Glue Sticks - An Acid-Base Indicator Activity

This short activity uses Elmer’s Disappearing Purple Glue as an interactive introduction to acid-base indicators.


Fun with Formula Stoichiometry: “Who poisoned Veronica Merriweather?”

"Who Poisoned Veronica Merriweather?" is a fun application of formula stoichiometry. Students who are placed in the role of a CSI lab sleuth helping to interpret chemical data to identify a murderer. Topics covered include formula stoichiometry, percentage composition, empirical and molecular formulas and gas chromatography–mass spectrometry.
