Abstract

A.c. polarographic measurements on aqueous solutions containing cadmium and fluoride ions have shown the existence of the species, CdF+ and CdF2, with stability constants (at 30° and an ionic strength of I.o) of 5.8 and 4, respectively. Reproducibility studies of a.c. techniques as a means for measuring changes in half-wave potentials (upon which the polarographic method for the determination of stabilities is based) have shown that the results obtained from a.c. polarographic measurements should be more accurate than those obtained by conventional d.c. polarography.
