原始语种摘要: The potentials of binary complexes of the Lauric acid ligand with various biologically vital divalent metal ions such as Mn(II), Co(II), Ni(II), Cu(II)and Zn(II) have been studied in 50% DMSO-water mixture at constant ionic strength by Bjerrum method. Hydrogen ion concentrations were measured and the formation of binary complexes was inferred from the corresponding potentiometric pH-titration curves. The metal to ligand mole ratio was maintained at 1:5 to facilitate the maximum number of ligands to the metal ion. The dissociation constant has been determined by the half-integral method and pointwise method and were found in good agreement with each other. The Metal-Lauric acid stability constants have been calculated and compared with the results.
