Product Details

Learn how a catalyst works by observing the color changes of pink cobalt ions. You’ll see the catalyst as it gets swept up in the oxidation of tartrate by hydrogen peroxide, changes into a green intermediate, and then reappears again at the end. A super demonstration to display rates of reaction, kinetics, catalysts and reaction mechanism. Teacher Demonstration Notes included.

Concepts: Kinetics, catalysts.
Time Required: 20 minutes

Correlation to Next Generation Science Standards (NGSS)

MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
HS-PS1-5. Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs.
