Recipe of the Week – Week 9: Hydrogen Peroxide

Continuing our new series of chemical recipes, we bring you week 9 – hydrogen peroxide (H2O2).

Remember that when preparing any of our recipes, you should always wear appropriate PPE.

What is hydrogen peroxide?

In it’s pure form, hydrogen peroxide is a little thicker than water and has a very pale blue appearance. For consumer use, it’s sold diluted with water and may appear clear – higher concentrations are used for industrial purposes.

The extra oxygen molecule oxidises so a low concentration has typically been used on skin to treat small cuts and scrapes as an antiseptic, killing germs. It is also used in bleaching and cleaning. A 3% concentration is widely available for household use; higher concentrations can be toxic.
