摘要:

AbstractThe dissociation constants foro‐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 calculatedpH‐meterically in different solvents. The dissociation constanspK1=4.10 andpK2=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 st
