Exercise 2: Write the schematic representation and reaction of the cell composed of SHE and cadmium electrode. Deduce the half-reaction potential of the cadmium electrode from the E°cell = - 0.403 V. Is the reaction spontaneous or not? Why or why not? If it is not spontaneous, how should the schematic representation be written to make it spontaneous? The magnitude of electrode potentials indicates the relative strength of the ionic species as electron acceptors (oxidizing agents); that is in decreasing strength, Ag* > H* > Cd²* > Zn2*.
