Product Details

The unique color changes will help your students understand the fermentation process. A glucose solution is inoculated with yeast in an Erlenmeyer flask and then connected with a tube to a gas-collecting chamber. As fermentation occurs, the depletion of the oxygen in the flask causes a dramatic color change in the indicator in the flask. Simultaneously, the carbon dioxide produced from the reaction causes a color change in a different indicator solution in the collecting chamber. Enough indicator solutions, yeast and sugar are provided to conduct the demonstration seven times. Detailed instructions and background information are provided.

Concepts: Fermentation, pH indicators.
Time Required: One class period
Note: A 250-mL flask, one-hole stopper, test tube, glass tube and plastic tubing are required for completion of the demonstration.
