How to Calculate Standard Cell Potential
E o cell = E o cathode – E o anode In this example, Zn(s) → Zn 2+ (aq) + 2e – is the oxidation, and therefore, it occurs on the anode. The E o anode = -0.76 V as per the table of standard reduction potentials. E o cathode, then is equal to -0.13 V, and the cell potential would be: E o cell = E o cathode – E o anode = -0.13 V – (-0.76 ...
