Aim The aim of this experiment is to discover how the rate of electrolysis is affected by the level of voltage. Possible Variables * Size of electrodes * Level of voltage * Time * Distance between electrodes * Molarity/Concentration of Electrolyte * Temperature of Electrolyte Plan As a group we have decided that our variable will be the level of voltage. We came to this decision because it will give us accurate results and a good range. For our experiment, we shall use the following pieces of equipment and apparatus: * 1 Power pack with adjustable voltage * 2 wires * 1 beaker * Copper sulphate solution (CuSO4(aq)) * 2 copper electrodes of equal weight (Cu(s)) * 2 crocodile clips * Top pan balance * Stop Watch (to time 5 minutes) Diagram Firstly we shall weigh each copper electrode and record their weights. Secondly, we shall set up our equipment as shown in the diagram. We shall then turn on the power pack, and wait for five...
