3. Metal ion complexation is known to affect the half-wave potential for the reduction of a metal ion. M+ + Hg+ne → M(Hg) MxAMAX (n-x)+ [1] [2] The relationship between the molar concentrations of the ligand CL and the shift in the half-wave potential is: = (E) E (-0.0592/n)logK - (0.0592x/n)logcL [3] Where (E) and E½ are half-wave potentials for the complexed and uncomplexed cation, respectively, K, is the formation constant for the complex, and x is the molar combining ratio of the complexing agent to cation. The following polarographic data were obtained for the reduction of Pb2+ to its amalgam from solutions that were 2.00 x 10-3 M in Pb2+, 0.100 M in KNO3, and different concentrations of the anion A. From the half-wave potentials, find (i) the formula of the complex, and (ii) its formation constant Kſ.
