(a) Interpretation: The dependence of E in some half-cell reactions on pH should be explained. Concept introduction: In an electrochemical cell there are two electrodes that can be observed. Electrodes are named according to their tendency of oxidation or reduction. If oxidation takes place on an electrode, that electrode is called anode. The removal of electrons takes place from the species present in anode. If reduction takes place on an electrode, that electrode is called cathode. The addition of electrons takes place to the species present in cathode. The electrode potential of cell is calculated from reduction electrode potential of cathode and anode as follows: E 0 cell = E 0 cathode − E 0 anode Nernst equation; E c e l l = E 0 c e l l − 0.0592 V z log Q Z = number of moles of electrons transferred in the cell.
