Chemistry Coursework Effect of increasing charge on Mass of Copper Deposited Diagram Method * I will fist weigh the cathode * I will then set up the apparatus as shown in the diagram * Then switch the power pack on * I will wait 10 minutes and then weigh the cathode, I will do this for 50 minutes every 10 minutes My Independent Variable is the Charge My Dependent Variable is the Mass of the cathode The controlled variables are the concentration of Copper sulphate and the temperature Prediction: I can predict that there will be a positive coloration between the increase of charge and the amount of copper produced at the cathode. Scientific Explanation: Current is the flow of electrons in a circuit - in the case of electrolysis the flow is towards the cathode and away from the anode. Within the solution, the current flows because of the presence of negative and positive ions. Copper sulphate is an ionic...
