· J. Chem. Eng. Data; (United States)
Densities of aqueous sodium hydroxide solutions were measured with a vibrating tube densimeter from 0.06 to 25.2 mol . kg/sup -1/ at temperatures from 278 to 318 K and pressures from 0.7 to 34.4 MPa. Values of the apparent molar volumes calculated from the measured densities are compared with available literature results at similar experimental conditions. The volumes are correlated as functions of temperature, pressure, and composition with the volumetric form of the ion interaction model to moderately high molalities; an arbitrary power series in m/sup 1/2/ is used at higher molalities. Specific volumes of NaOH(aq) are tabulated at smoothed temperatures, pressures, and molalities. Standard-state partial molar volumes, expansivities, compressibilities, and heat capacities calculated from the treatment are consistent with the reaction thermodynamic properties of water and available values for NaCl(aq) and HCl(aq).
