Potentiometric Determination of the Stability Constants of 2-, 3- and 4-Hydroxybutyrato Complexes of Cobalt(II), Nickel(II), Cadmium(II) and Lead(II)

The stability constants of the title complexes were determined potentiometrically using a quinhydrone electrode at (298.2 ± 0.1) K in buffer solutions of ionic strength 2 mol dm-3 adjusted by addition of NaC104• The numerical values of stability constants were evaluated from experimental data by computer program based on a weighted least squares method
