Spectrophotometric and potentiometric determination of the protonation constants of dithiocarbazates and studies on some of their metallic chelates.
The protonation constants of 2-methyldithiocarbazate, 3,3-dimethyldithiocarbazate and 3-methyl-3-phenyldithiocarbazate, have been determined potentiometrically (I = 1.00M) and spectrophotometrically (I = 0.01M) at 25 degrees in aqueous solution. The analytical properties of the reagents have been studied, and also the compositions of some of their insoluble metallic chelates.
