WebbWhen that is done, it is clear that the theoretical standard cell potential for the zinc-copper cell is 1.10 volts. In general, a real voltaic cell will differ from the standard conditions, so we need to be able to adjust the calculated cell potential to account for the differences. This can be done with the application of the Nernst equation.
