Electrode Potential
Electrode Potential is denoted as EMF ( electro motive force ). EMF of
any electrolytic cell is the sum of the EMF produced at two electrodes.
EMF cell = Higher reduction potential - Lower reduction potential
Potential of a single electrode cannot be measured directly. It is measured
by connecting reference electrode ( with known electrode potential ).

Similarly the standard potential of any electrode can be determined if the
EMF of the cell is given. To calculate the standard potential of the zinc
electrode if EMF of the cell is 1.559 V in Zinc - Silver electrode,
