Job's method of continuous variations as well as molar ratio method, as applied to two phase systems, have been used in order to establish the stoichiometry of vanadi­um(V)-N-arylhydroxamates extracted from 2-8N hydrochloric acid solutions. The metal to ligand ratio is found to be 1:2 in all the instances and the stability constants are of the order of 10⁸to 10⁹. The wavelength of maximum absorption and molar absorptivi­ty for each complex is also given.
