The (p, V, T) properties of concentrated aqueous electrolytes I. Densities and apparent molar volumes of NaCl, Na2SO4, MgCl2, and MgSO4 solutions from 0.1 mol·kg−1 to saturation and from 273.15 to 323.15 K

Apparent molar volumes and heat capacities of aqueous magnesium chloride and cadmium chloride at temperatures from 278.15 K to 393.15 K at the pressure 0.35 MPa: a comparison of ion–ion interactions

“…Figure 1 shows our results compared with those of Perron et al, (9) Chen et al, (10) and Lo Surdo et al (11) at T = 298.15 K and Saluja and LeBlanc (12) at various temperatures. The agreement of our results with those of previous investigators is excellent, although those of Lo Surdo et al (11) are lower by about 1.3 cm 3 · mol −1 .…”

“…Figure 1 shows our results compared with those of Perron et al, (9) Chen et al, (10) and Lo Surdo et al (11) at T = 298.15 K and Saluja and LeBlanc (12) at various temperatures. The agreement of our results with those of previous investigators is excellent, although those of Lo Surdo et al (11) are lower by about 1.3 cm 3 · mol −1 . Our values differ from those calculated using the equations of Wang et al (13) at 278.15 < (T /K) < 393.15 and p = 0.35 MPa by less than ±1.0 cm 3 · mol −1 for m > 0.2 mol · kg −1 and by less than ±2.2 cm 3 · mol −1 for m < 0.2 mol · kg −1 .…”

“…However, equations (11) and (12) can be used to represent the data by explicit inclusion of the (arbitrary) temperature-dependent coefficient (c 7 +c 8 ·T ) with the Debye-Hückel term in equation (11). Deconvolution of our C p,φ results in terms of the contributions of each complex species in equation (1) requires that one determine the concentrations and activity coefficients of each species at each T and m, and that is beyond the scope of this investigation.…”

Volumetric properties of water, and solutions of sodium chloride and potassium chloride at temperatures fromT= 277.15 K toT= 343.15 K at molalities of (0.1, 0.5, and 1.0)mol·kg−1

“…(24,61,70,77) The usual reasons were large temperature gaps and different molalities. In only a few investigations were measurements of density performed at closely spaced temperature intervals and at fixed molalities {1 K intervals, m(NaCl) = 0.11425 mol·kg −1 and m(KCl) = 0.11528 mol·kg −1 from T = 293.15 K to T = 313.15 K by Millero and Drost-Hansen; (61) 5 K intervals, m(KCl) = 0.1355 mol·kg −1 from T = 278.15 K to T = 318.15 K by Bull and Breese; (62) m(NaCl, or KCl) = (0.05, 0.1, 0.5, 1.0, 2.0, 3.0, 4.0, and 5.0) mol·kg −1 from T = 288.15 K to T = 328.15 K by Isono; (69) m(NaCl) = 1.0 mol·kg −1 and m(KCl) = (0.5 and 1.0) mol·kg −1 from T = 298.15 K to T = 318.15 K by Romankiw and Chou (71) }.…”

“…In the original paper of Lo Surdo et al (1982) an alternate formulation based on the work of Kell (1975) was used for the density of pure water. The difference is <10 ppm over the temperature range 0 to 50 °C.…”
