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. 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.
