This microchemistry rainbow colored lab is appropriate for introducing pH, qualitative chemistry, acids and bases, and solutions to grades 6-12. I use it in my pre-ap chemistry class as an introduction to acids, bases, pH and titration. You could also use it to open the year in chemistry, with middle school gifted and talented students, or in IPC or physical science.
Inexpensive, easy to set up and requiring no real chemicals other than hydrochloric acid, this activity can be completed in a 50 minute period. The bundle includes a power point presentation on acids and bases for classes with or without lab books and a version with or without an introduction. Includes color charts.
