Chromatography Tie Dye

Saturday, January 30, 2021

Have you ever spilled water on a newspaper?  Did you notice that the ink runs and spreads on the page? In this session, we will learn about ink solubility and a laboratory technique called chromatography, which allows you to separate a mixture. Then, we will explore the technique by making a colourful chromatography tie dye project. Join us for some creative chemistry!

Preparation: a few rubber bands, 2-5 plastic cups, a colourful assortment of permanent markers (dollar store ones work well), an eyedropper, 70% or higher isopropyl alcohol (rubbing alcohol), white fabric that can be dyed (eg. t-shirt).  You will also want to protect your workspace.
Expert: Carine Nemr is completing her PhD in Chemistry at the University of Toronto.
