An investigation into the factors which effect The electrolysis of copper sulphate solution. Task: My task is to find out how we can increase the mass of the cathode, and how different methods affect it. We know that by passing an electric current through an aqueous copper sulphate solution, that ions passing through this solution will cause anions to be dissolved into the solution from the anode, and deposited on the cathode. Diagram: Equipment needed: * 2 copper strips (anode and cathode) * 50ml Copper sulphate solution (aq) * 1 voltmeter * 1 power supply * 1 variable resistor Method: First, I shall weigh the anode and cathode, and label them. I shall then set up the experiment, as shown above, and set the current at 0.1 amps. I shall then leave it for 5 minutes for electrolysis to take place, before weighing the anode and cathode, and increasing the current to 0.2 amps, re-weighing the anode and cathode,...
