We're all familiar with the colors of the products we use every day. But what we often don't know is their relationship to chemistry. Chemistry experiments can be used to mix and match colors to obtain a variety of results. The multicolored milk experiment is a case in point.
What's it all about?
Bright, changing colors always catch the eye. But did you know that some of these color changes are deeply rooted in chemistry? These fascinating at-home chemical experiments based on color changes according to the qualities of the environment are sure to arouse children's curiosity.
What's involved?
It's all about :
- Experiment with dyes and liquid soap
- Learn how thymol blue (a chemical substance that changes color according to the pH of a solution) reacts to pH changes in a solution.
- Concoct a magic liquid that changes color according to pH (hydrogen potential: a measure of the acidity or basicity of a solution).
This is an excellent learning moment in colored chemistry, as it teaches us about :
- Surface tension (a physical property of liquids that describes the force acting on the liquid's surface)
- Acids and alkalis (chemical substances that dissolve in water to generate hydroxide ions)
- pH indicators
