Kit Disappearing Rainbow Demo Kit

Not yet rated

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. These can be combined in various ways to create all the colors of the rainbow. 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.
