An investigation to see how voltage affects The electrolysis in a copper Sulphate solution using copper electrodes. Aim To find out how the voltage affected the electrolysis in a copper sulphate solution by weighing the amount of copper that was on the anode and the cathode and then comparing the difference from before the electrolysis. Theory Electrolysis is the process of decomposing the compounds by electrical energy and an element is produced at each electrode. In this case I have chosen copper sulphate solution to electrolyse. In the experiment when the solution is being electrolysed it starts to decompose and at cathode there is copper formed and oxygen at the anode. This is caused by electricity from the power supply, which has caused a chemical change. The reaction, which occurs at the cathode, is: Cu2+ (aq) +2e- › Cu (s) The reaction, which occurs at the anode, is: Cu (s) › Cu2+ (aq) + 2e- Variables The possible independent variables...
