Does the Magnitude of current affect the rate of electrolysis? Plan The circuit that I shall use in this experiment will be built as the diagram shows. During electrolysis the copper electrodes either receive from, or donate to, copper ions infrom the copper sulphate electrolyte solution. If the electrolysis is affected by the magnitude of the current flowing this could be demonstrateden by measuring the current and weighing the electrodes before and after a fixed period of time. The positive ions of copper in solution will deposit at the negative cathode which will therefore gain in weight whilst the positive anode will release copper ions into the electrolyte and so lose weight. Method With the power on I shall adjust the variable resistor to give the exact current flow required (I can do this by observing and recording the ammeter reading). The current flows that I will need set in(on different experiments) are: *...
