What Factors affect the amount of copper deposited onto the electrode during electrolysis? Aim-I would investigate how changing the voltage would affect the rate of electrolysis. Introduction-Electrolysis is the decomposition of a substance by passing an electric current. Some substances are strong and others weak, depending on how they can be decomposed. E.g. sodium chloride is a strong electrolyte and water is a weak electrolyte. Oil is not an electrolyte because it does not decompose by passing an electric current. Apparatus-Power pack, Wires, Voltmeters, 100ml beakers, Croc clips, Weighing machine, Safety goggles, Measuring Cylinder, Copper Electrodes and Copper sulphate solution 0.50M. Method-I would place 40 cm³ of copper sulphate in a small beaker. The strength of the copper sulphate would be 0.50M. I am also going to place 2 electrodes in the beaker held by crocodile clips, which would be connected to a power pack. First I will always weigh the electrodes....
