Ionization constants for acid functions of D-penicillamine, L-cysteine, thiomalic acid, and thioglucose were measured by pH titration at 37 degrees and 0.15 M ionic strength. Chelate formation constants for these ligands with calcium(II), iron(III), and gold(I) were then determined under the same co
## Abstract The complexes of diphenylcarbazone with zinc, nickel and cobalt are studied spectrophotometrically in a 50 volume percent aqueous acetone medium. The wavelength of maximal absorbance is situated between 520β525 nm. The three complexes show a 1:2 stoichiometry as derived independently fr
