title: Polarographic studies of cadmium, zinc and manganese(II) iodide complexes in acetonitrile.
abstract: Cadmium, zinc and manganese(II) iodide complexes have been studied polarographically in acetonitrile and the electrode reactions for these complexes discussed. The overall stability constants of the iodide complexes of these metal ions were evaluated and corrected for the effect of the ion-pairing electrolyte. The values for log beta(4) of CdI(4)(2-) and ZnI(4)(2-) are 26.2 and 18.4 respectively and the values found for the Mn(II) iodide complex are log beta(1) = 3.5, log beta(2) = 5.6, log beta(3) = 7.8, log beta(4)= 10.0, log beta(5) = 12.2 and log beta(6) = 14.4. Within certain limits, the wave-height for each complex is proportional to the metal concentration.
