I am going to test the aim in this test by setting up a beaker with two carbon rods in it. One will be a anode and one will be a cathode. These rods will have six volts flowing through them. The beaker will be half filled up with copper sulphate which is a blue liquid and will act as a electrolyte.

To save time and effort I will used a power supply instead of using some batteries. For safety the power supply will be locked at six volts.

I will then turn the power on and wait and see if the cathode has gained any weight by picking up pure carbon from the impure carbon on the anode.

Length of time I leave the power on

I have chosen to change the length of time I will leave the power

I will use a beaker to hold all the important equipment together.

I will use a power supply to give power to the circuit in a easy safe way.

All this relies on the positive and negative charges either repelling or attracting each other.

I will use copper sulphate to let the metal transfer from the anode to cathode in.

The other variables in the list I will try my hardest to keep the same.
