Abstract An electron-paramagenetic resonance and spectrophotometric study has been made of the composition of mixed chelate compounds of titanium(III)-ethylenediaminetetraacetic acid (EDTA) and organic acids. The existence of three titanium(III)-EDTA complexes in solution has been established. The complex formation of titanium(III)-EDTA with oxalate, tartrate, citrate and lactate has been confirmed, and the ratio of the oxalate has been established. Structures for the complexes have been proposed, probable equilibrium mixtures of complexes at various pH values have been discussed and new procedures have been proposed for the detection of chelate compounds in solution.
