Effect of Complex Formation on Electrode Potentials

One of the methods by which the formation constants of metal complexes can be determined involves the measurement of electrode potentials of half cells of the type M + ne M in a series of solution of varying ligand concentrations. 

The material presented in this chapter is based on the assumption that achievement of equilibrium is rapid. It must be pointed out, however, that redox processes are sometimes quite slow. 

7-1 a) Develop the diagram for pE vs. pH for the HCIO, CI2, CF System b) Using appropriate pE values from (a), develop pE vs. logC for this system at pH 0, 5, and 8, using different line styles to different distinguished results at each pH (If QPRO 3.0 is available, use the 3D graphical option fra 2 or 3 pH values).
