Abstract:

The dissociation constants for different carboxyphenyl-hydrazo-β-diketones ligands as well as the stability constants for divalent metal complexes of Cu(II), Ni(II), Zn(Il), Mn(II) and Cd(II) ions, have been calculated pH-metrically in 75% dioxan-water solvents The relations between KMA and both second ionization potential and dissociation constants are discussed.
