The electromotive force measurement permitted us to determine the chemical speciation of the complexes formed. In the vanadium(III)-dipicolinic acid-lactic acid system the complexes detected were: V(dipic)(lac), V(dipic)(lac)(OH)− and V(dipic)(lac)$(\mathrm{OH})_{2}^{2-}$. In the vanadium(III)-dipicolinic acid-oxalic acid system the observed complexes were: V(dipic)(ox)−, V(dipic)(ox)(Hox)2− and V(dipic)$(\mathrm{ox})_{2}^{3-}$. In the vanadium(III)-dipicolinic acid-citric acid system the complexes V(dipic)(Hcit)−, V(dipic)(cit)2−, V(dipic)(cit)(OH)3−, V(dipic)(cit)$(\mathrm{OH})_{2}^{4-}$ and V(dipic)(cit)$(\mathrm{OH})_{3}^{5-}$ were detected. Finally in the vanadium(III)-dipicolinic acid-phosphoric acid system the complexes V(dipic)(H2PO4) and V(dipic)(HPO4)− were observed. The UV-vis spectra allowed us to perform a qualitative characterization of the complexes formed in aqueous solution.
