Have a little read: ... Electrolysis Using Copper Sulphate And Copper Electrodes Introduction In this experiment copper sulphate will be electrolysed using copper electrodes to find the loss of mass of the anode. The copper anode will be weighed before and after the experiment. Each time the experiment is done the time will be increased by 2.5 minutes until 25 minutes is reached. So the first experiment will last 2.5 minutes and the second 5 minutes. The results will be plotted on a graph of loss of mass against time. Aim To find the loss of mass of anode when electrolysing copper electrodes using copper sulphate solution for different times. Background Information Electrolysis is used to purify copper.
