A cyclic hydroxamic acid, 2–hydroxyquinoline–N–oxide and an aromatic hydroxamic acid, benzohydroxamic acid were obtained in the form of free acids. Their acid dissociation constants and a total of seventy of the formation constants for twenty five complexes formed by these two hydroxamic acids with rare earth metals and yttrium in aqueous solution have been determined by Bjerrum potentiometric titration technique.
