I predict that the positive electrode will get heavier after every 5 minutes where as the negative electrode will get lighter. I think this will happen because the positive electrode gives out the impure copper and the negative electrode takes in the impure copper. Method 1. Weigh the electrodes. 2. Make up the circuit with a bulb. 3. Put the electrodes in the copper sulphate solution. 4. Turn on the circuit. 5. Time it for 5 minutes. 6. After 5 minutes stop the current and the stop watch. 7.
