Thermodynamic Properties of the NaBr+H2O System (original) (raw)

Equations that described the thermodynamic properties of the NaBr+H2O system were obtained from a fit to experimental results for this system. The experimental results included in the fit spanned the range of temperature of approximately 260 to 623 K and the range of pressure from the vapor pressure of the solution to 150 MPa. New equations and/or values for the following properties are given in the present work: 1) the change in chemical potential with respect to temperature and pressure for NaBr(cr), valid from 200 to 900 K, 2) Δ_f_ G_0_m and Δ_f_ H_0_m for formation from the elements for NaBr(cr) for 298.15 K and 0.1 MPa, 3) Δ_f_ G_0_m and Δ_f_ H_0_m from the elements, as well as S_0_m and C_0_p,m, all for 298.15 K, 0.1 MPa for NaBr⋅2H2O(cr), 4) the change in chemical potential for both NaBr and H2O in NaBr(aq) as a function of temperature, pressure, and molality, valid from 260 to 600 K and from the vapor pressure of the solution to 150 MPa.
