Mn, Fe, and Co in the +2 and +3 oxidation states all form hexaaquacomplexes in acidic aqueous solution. The reduction reactions of the three species are represented schematically below, where the water ligands are not shown for simplicity. It is an experimental fact from elec- trochemistry that Mn2+ and Co²+ are more easily reduced than Fe3+; that is, they will more readily accept an elec- tron. Based on the electron configurations of the ions involved, explain why Fe³+ is harder to reduce than Mn2+ and Co²+. Mn3+ + e – Mn²+ Fe* + e –→ Fe²+ Co³+ + e → Co²+

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.
