Chemistry Prac: Investigate the Catalysed Decomposition of Hydrogen Peroxide. Can ne1 explain or give ideas???

Question

Hey

Iv been away sick for a while and i got back to school only to recieve this chem prac. I have no idea what this means and have no idea how to come up with my own investigation. We have to completely design the experiment in-class with only the materials we request. Help!

Thanks in advance

Answer 1

Don't have time to give detailed answer, but here are some ideas........

H2O2 decomposes to H2O and O2. You need to identify something that will catalyze this decomposition - the enzyme catalase, for example.

Remember that a catalyst is not destroyed in a reaction............but one might look for a connection between catalyst level and reaction speed.

The other thing you need is some way to measure the concentration of H2O2 in solution. KMnO4 comes to mind - See:

Sorry, I cannot do it all for you.....
