M18Q5: Standard Cell Potentials, E° - Unizin
To calculate the cell voltage, E ° cell = E ° cathode - E ° anode, using the values from the standard reduction potential table. For example, in the Zn/Cu cell, the Zn is connected to the black wire (anode) and the Cu is connected to the red wire (cathode). For copper, the E° = 0.34 V. For zinc, the E° = -0.76 V.
