Unformatted text preview: increases, so does the cell potential. In part 2 of this experiment, we tested the effects of concentration on cell potential. Our measured and calculated results were very similar. We found the cell potential to be .488V with equal concentrations. It then increased to .527V with .1M of Pb and decreased to .455V with .1M Cu. This demonstrates that when the lower concentration is in the anode, the cell potential will increase and when it is in the cathode, it will decrease. Some possible sources of error in the experiment could have been the surfaces of the lead and copper electrodes. If there was any residue left from oxidation or the acid, it could affect the readings on the voltmeter. Another error could be in the salt bridge. If the electrons could not flow freely, it would also affect the cell potential reading....
