Disappearing Rainbow Demonstration
Product Details & Documents
Demonstrate the concepts of Indicators and Acids and Bases!
- Students see reactions in real time
- Combine colors to create all the colors of the rainbow
Three indicators are used in conjunction with acids and bases to create a rainbow of colors. In a basic solution, phenolphthalein is red, p-nitrophenol is yellow, and thymolphthalein is blue. If done correctly the students only see the acid or base being poured, which adds to the impressive display. There are enough materials to complete the demonstration 7 times.
