SRA039 - Propanone oxidation with a copper catalyst
A hot copper plate is placed into an atmosphere containing propanone and the reaction takes place on the surface of the copper foil, making it appear red hot. As the concentration of air in the flask changes, so do the colours on the glowing hot copper foil. This demonstration is an example of heterogeneous catalysis in the gas phase.

Note:- These activities are designed to be carried out individually as part of a lesson conducted in a secondary school science laboratory. The procedures are not intended for use in other contexts – for example in a primary school classroom or other non-science or non-school setting. 

The activities should not be used to create a ‘whizz bang’ science show. 

Experience suggests that using a number of activities one after the other in this way gives rise to unpredictable additional risks which the individual procedures may not manage appropriately.
