Abstract:

Hints & Tips:

- It may be more practical to supply the class with ready-cut lengths of potato, using a chipper.

- When collecting gas over water it is sometimes easier to use a flaxible tube on the end of the conical flask and feed it through a beehive shelf sitting underneath the upturned measuring cylinder in the trough.

- You need to do a serial dilution of the hydrogen peroxide for this practical.
