- 中文摘要: The dissociation constants for o-carboxyphenylhydrazoethylacetoacetate (o-CPHEA) ligand, as well as the stability constants for the divalent metal complexes of Cu, (II), Ni (II), Co(II), Zn(II) and Cd(II) ions, have been calculated pH-meterically in different solvents. The dissociation constants pK/sub 1/=4.10 and pK/sub 2/=10.55 of the insoluble organic ligand are calculated in aqueous medium. The effect of solvents, the relation between stabilities and both electronegativities and ionization potential are studied.
