Abstract

The formation of vanadium(V) complexes has been examined potentiometrically by the method of acidimetric titrations of aqueous solutions at pH 7-5. The composition has been determined and the formation constants have been calculated for the oxalate chelates VO₂Ox₂^3- and VO₂Ox . (OH)^2-, the maltol chelate VO₂A₂^-, the ternary complex VO₂OxA^2-, and for binuclear and tetranuclear complexes with tartarate, glycolate, sorbitol, and mannitol. The structure of the complexes is discussed in terms of the consumption of protons for their formation.
