Electrolysis Investigation using Copper Electrodes Aim The aim of this experiment is to find out whether varying the amount of current affects the mass of copper plated. Prediction I predict that the bigger the current the greater the mass of copper plated will be. Therefore the relationship between the current and the mass of copper plated will be directly proportional, so if I double the current, the mass of copper plated will also double. I think this because during electrolysis, the number of electrons being used up at the cathode by the positive ions must be equal to the number of electrons released at the anode by the negative ions. Therefore if the current, i.e. the number of electrons flowing at any given time, is increased, the number of ions discharged must be increased proportionally. The same applies if the current is passed for a longer time. The mass of a substance released is...
