Abstract
Abstract The effect of p -toluenesulfonate and trifluoromethanesulfonate supporting electrolytes on the polarographic reduction of some alkaline earth and transition metal ions in N,N-dimethylformamide and acetonitrile has been investigated. Trifluoromethanesulfonate behaved similarly to perchlorate in dimethylformamide, while the half-wave potentials in p -toluenesulfonate supporting electrolyte shift to more negative potentials than those in perchlorate. in acetonitrile, the half-wave potentials shift to more negative potentials in trifluoromethanesulfonate than in perchlorate. The effect of the supporting electrolyte on the shift of the half-wave potential can be explained as the ion-pair formation between the divalent cation to be reduced and the supporting electrolyte anion.
