Abstract

The solubility equilibria between Cd(II) and 2-mercaptoproprionic acid in 3.0 M NaClO4 at 25°C have been studied by e.m.f. The e.m.f. measurement with both glass and Cd(Hg) electrodes in the range 2.5 < pH < 4.8 were made in solutions where a solid phase coexists with soluble complexes CdqAp. Free ligand and metal ion concentrations were calculated in order to determine the solubility product of CdA (eqn 5). From the values of the formation constants for the soluble complexes and the solubility product, the solubility constants kspq have been computed. A general equation for the redissolution of the precipitate is proposed and a set of equilibrium constants is given. © 1978.
