The solubility of plutonium trifluoride was measured in mixtures of nitric and hydrofluoric acids of various molarities and tetrafluoride in nitric acid. The effect of fluoride ion on the solubility is discussed and an attempt made to estimate the solubility product of each compound. On the basis of available data, the solubility products appear to be trifluoride 2.5 x 10/sup -16/ and tetrafluoride 6 x 10/sup -20/. The solubility of plutonium(IV) oxalate was determined in mixtures of nitric acid up to 3.52M and oxalic acid up to 0.6M. The minimum solubility occurs in 1M nitric acid to O.O1M oxalic acid, but there is evidence that after 2 to 3 weeks' eqailibration in this mixture an abnormal effect leads to anoma-. lous solubilities.
