Product Details

The visible spectrum has been displayed many ways, but never quite as spectacularly as this! Take seven different dry chemical mixtures, and add each to a separate beaker. Pour a clear liquid into each beaker. In less than a minute, the large pH change at the end of this clock reaction causes a blooming of the seven rainbow colors. A wonderful introduction to acid–base buffers. Teacher Demonstration Notes included.

Concepts: Clock reactions, pH indicators, buffers.
Time Required: 15 minutes
Chemicals Provided: Formaldehyde solution, isopropanol solution and seven dry indicator mixtures.
