Study in Some Heterochelates. III. Cu(II), Ni(II), Zn(II) or Cd(II)+Histidine or Ethylenediaminetetraacetic Acid+Polyphenols Systems

An extension of Irving-Rossotti technique has been applied to study the formation constant of mixed ligand complexes as follows:[MA]+[L]\ightleftarrows[MAL] where M=Cu(II), Ni(II), Zn(II), and Cd(II), A=histidine or ethylenediaminetetraacetic acid and LH2= catechol, pyrogallol or 2,3-dihydroxynaphth...

Summary:An extension of Irving-Rossotti technique has been applied to study the formation constant of mixed ligand complexes as follows:[MA]+[L]\ightleftarrows[MAL] where M=Cu(II), Ni(II), Zn(II), and Cd(II), A=histidine or ethylenediaminetetraacetic acid and LH2= catechol, pyrogallol or 2,3-dihydroxynaphthalene. The values obtained for the mixed ligand formation constants KMAL are found to be less than the first formation constant KML, in the binary systems.
