Product Description

By: Steve Spangler
Regis University, Denver, CO

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. Enough materials are included to perform the demonstration seven times.
Concepts: Clock reactions, pH indicators, buffers.
Time Required: 15 minutes
Chemicals Provided: Formaldehyde solution, isopropanol solution and seven dry indicator mixtures.
