Stability Constants Determination of Mandelate Complexes of Cobalt(II), Nickel(II) and Zinc(II)

Sa？etak Stability constants of mandelate (2-phenyl-2-hydroxyacetate) complexes of cobalt(II), nickel(II) and zinc(II) were determined. potentiometrically using glass and quinhydrone electrodes at 25.0 ± 0.1 aC and ionic strength 2 mole dm" (sodium perchlorate). The numerical values of stability constants were evaluated from experimental data by a computer program based on a weighted least squares method
