Product Details

Produce a rainbow of colors by demonstrating how hydrogen peroxide can both oxidize and reduce. Hydrogen peroxide (which is a colorless solution) will cause another colorless solution to turn yellow then red-orange. It also has the ability to make a purple solution go through a series of color changes with the end solution being colorless. Teacher Demonstration Notes included.  

Concepts: Oxidation–reduction.
Time Required: 15–20 minutes
