Investigation to find out the Effect of Current on the Mass Deposited at the Cathode The experiment I will be carrying out is aimed to observe the amount of Copper (Cu) metal deposited during the electrolysis of Copper Sulphate solution (CuSo4) using Copper electrodes, when certain variables of controlling the current, maybe with a computer, and also I could use a thermometer to show the change in temperature, so that it can be monitored.
