CORRELATION OF TURBIDITY AND ACTIVITY DATA: II. TUNGSTOPHOSPHORIC AND TUNGSTOSILICIC ACIDS
Abstract
Turbidity and differential refractive index data are given for 12-tungstosilicic and 9tungstophosphoric acids up to concentrations of about 1 g/ml at 546 mmu. Additional data at 436 mmu are given for 12-tungstosilicic acid. Isopiestic vapor pressure data from which the activities of both solvent and solute are determined are given for 12-tungstosilicic acid. Also, densities of 12-tungstosilicic acid are reported. Activities and densities of 9-tungstophosphoric acid solutions obtained previously were used. Excellent agreement is obtained between activities determined from each of the two techniques, light scattering and isopiestic vapor pressure. Turbidities determined by these 2 techniques also agreed. (Author 0
