- Part A - Shows the 4 experiments experiment
Part B - Discusses how to predict the products of electrolysis for 4 solutions
1 - Sodium Sulphate
2 - Sodium Chloride
3 - Copper Chloride
4 - Copper II Sulphate

A FEW NOTES
- The copper collected on the bottom of the electrode - you can see it as a paler colour. It's not very clear, but chunks of it were falling off in the solution and collecting underneath the electrode.
- Any suggestions on how to collect the gases better then please let me know. As far as I understand, most of the oxygen probably reacts with the carbon in the electrode and becomes carbon dioxide. This may not create so many bubbles because it dissolves in the solution?
