Summary

Ti(III) and Ti(IV) form complexes, at pH values of under 2.5, with ethylene di-amino-tetra-acetate (Y−4) with the probable formula TiY− and TiY, which are reduced reversibly and independantly of pH at the dropping Hg-electrode. Temporary values are given for the dissociation constants. At higher pH values, the electrode processes are irreversible and dependant on Ph. From this fact, and from the decrease in wave height, the presence of complexes containing oxygen and numerous nuclei is concluded.
