I have chosen to do electrolysis of Copper Sulphate with copper electrodes rather than the alternatives, sulphuric acid with graphite electrodes, because then I would have to collect gas (which is more difficult) rather than a solid.

Chemistry Coursework - Plan I have chosen to do electrolysis of Copper Sulphate with copper electrodes rather than the alternatives, sulphuric acid with graphite electrodes, because then I would have to collect gas (which is more difficult) rather than a solid. Initial Aim To find out how a change in current that passes through a copper sulphate solution changes the amount of product at the cathode. This is what I intially investigated in my preliminary experiment. I found out that this was was more problematic than verying time would be because when the current got higher the temperature within the circuit changed and as a result the current was not constant. I decided that time would be much easier to vary. New Aim To find out how the amount of time for which a current passes through a copper sulphate solution changes the amount of product at the cathode. Hypothesis I think that the increase in time...
