Abstract: The thermodynamic mixed ionization constants, pKof N-m-chlorophenyl-p-substituted benzohydroxamic acids and glycine have been determined in 0.083 to 0.24 mole fraction of dioxane (n2) 25°C. The mixed pK are correlated with the Hammett equation. The determined stability constants have been found to follow the order Pd(II) > Cu(II) > Ni(II) > Zn(II)> Co(II) > Fe( II) > Mn(II) and these also follow the order of basicities of the ligands. The linear free-energy relationship for the particular set of metal ions and the set of ligands is calculated and compared.
