The Effect of Standard Electrode Potential on Battery Voltage

The purpose of this experiment was to determine what combination of anode and cathode would give the maximum voltage. A higher voltage means that the batteries can be used as a inexpensive and clean source of power for small electronic devices. The method that was used to test two different types of electrolytes and different combinations of metals which were anodes and cathodes and to find out what voltage was produced. The results were that the anode Magnesium (Mg) and the cathode Brass produced the highest voltage of the simulated seawater batteries while the anode Magnesium (Mg) and the cathode Copper (Cu) produced the highest voltage in the Copper Sulfate (CuSO4) and Zinc Sulfate (ZnSO4) batteries. It was concluded that standard electric potentials do not accurately predict the voltage that a battery will produce.
