Chemical Concept Demonstrated

Catalytic oxidation

Demonstration

A penny is heated to glow red-hot and hung over acetone.

Observations

The penny glows until all of the acetone is consumed.

Explanation

The copper penny catalyzes the oxidation of the acetone to its combustion products of CO₂ and H₂O. However, although the combustion products are being formed, keep in mind that combustion itself is not taking place. The copper is simply providing a catalytic surface for the acetone to react upon.

The copper, being a catalyst, is not expended during the reaction.
