This I/GCSE Chemistry blog post will look into the necessary practical for showing catalytic reactions, let's get to it!
EXPERIMENTAL MEASUREMENT OF CATALYTIC ACTION
Take a test tube half full of hydrogen peroxide and add a little manganese(IV) oxide or a tiny piece of raw liver. Manganese(IV) oxide is readily available in a chemical laboratory.
A student working at home will find some in an old torch battery.
Break open the battery and use a pinch of the black powder inside the battery.
This contains some manganese(IV) oxide.
Notice how, in the presence of a catalyst, the hydrogen peroxide starts to decompose immediately at room temperature.
Check with a glowing taper to make sure that the gas coming off is oxygen.
You could measure the volume of oxygen produced at various times from the start of the reaction and plot them on a graph.
You would need to collect the oxygen in some container that would give you measurements of volume.
You might invert a measuring cylinder full of water over the end of a tube leading from the hydrogen peroxide.
No catalyst can make a reaction occur that was not possible before. Catalysts make existing reactions easier, they DO NOT create new ones. They are not used up during the reaction.
That is all to know about the experiment!
