“…The viscosity of 30 wt-% sodium carbonate solution was extrapolated based on these data. The data of Gonc -alves and Kestin (1981) were not used for sodium carbonate solutions, because they measured viscosities only up to 15 wt-% sodium carbonate. The viscosity data for aqueous sodium carbonate of Gonc -alves and Kestin (1981) and Roberts and Mangold (1939) agree well with each other.…”

“…A literature survey revealed that the number of measurements [24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43] reported for the density of Na 2 CO 3 (aq) cover very limited ranges of temperature (up to 383 K) and pressure (up to 30 MPa). Shilovskaya and Lenkova [30] measured the density of Na 2 CO 3 (aq) in the temperature range from 293 to 353 K and for concentrations between 0.1 and 0.4 mol l −1 .…”

“…The uncertainty of the measurements is within 0.3%. The measurements by Goncales and Kestin [35] were performed at atmospheric pressure in the temperature range from 293 to 333 K and at concentrations from 0.3087 to 1.6892 mol kg −1 with pyknometer. Hershey et al [41] measured the densities of Na 2 CO 3 (aq) at temperatures from 273 to 318 K and at concentrations between 0.05 to 1.0 mol kg −1 .…”

Apparent and Partial Molar Volumes / Density / B-Coefficient / Sodium Carbonate / Viscosity / WaterDensity of five (0.124, 0.334, 0.706, 1.055, and 1.123) mol kg −1 and viscosity of seven (0.124, 0.2918, 0.334, 0.706, 0.8472, 1.055, and 1.123) mol kg −1 binary aqueous Na 2 CO 3 solutions have been measured with a constant-volume piezometer and capillary flow techniques, respectively. Measurements were performed at pressures up to 52 MPa for the density and 40 MPa for the viscosity. The range of temperature was from 299 to 577 K for density and from 293 to 478 K for the viscosity. The total uncertainty of density, viscosity, pressure, temperature, and composition measurements was estimated to be less than 0.06%, 1.6%, 0.05%, 15 mK, and 0.02%, respectively. Apparent molar volumes were derived using measured values of density for the solutions and for pure water calculated with IAPWS formulation. The effect of the thermodynamic variables (temperature, pressure, and concentration) on density, apparent and partial molar volumes, and viscosity of Na 2 CO 3 (aq) solutions was studied. The derived apparent molar volumes have been interpreted in terms of the Pitzer's ion-interaction model of electrolyte solutions to accurate calculates the values of partial molar volumes at infinite dilution V ∞ 2 and the second (B V ) and third (C V ) virial coefficients for the apparent molar volume as a function of temperature. The viscosity data have been analyzed and interpreted in terms of extended Jones-Dole equation for the relative viscosity (η/η 0 ) of strong electrolyte solutions to accurate calculate the values of viscosity A-and B-coefficients as a function of temperature. The Arrhenius-Andrade parameters η A and b = E a /R (where E a is the flow activation energy) were calculated using present experimental viscosity data. The effective pressures P e due to the salt (Na 2 CO 3 ) in water in the TTG (Timmann-Tait-Gibson) model were calculated from present viscosity measurements.

“…The best fit of all the chemistries was for four sets of NaHCO 3 temperature data (0, 5, 15, and 25°C) (Hershey et al, 1983), where the 95% confidence interval was Ϯ 3.60 ϫ 10 -5 g cm -3 . The worst fit of all the chemistries was for four sets of K 2 CO 3 temperature data (0, 10, 20, and 25°C) (ICT, 1928;Goncalves and Kestin, 1981), where the 95% confidence interval was Ϯ 2.15 ϫ 10 -3 g cm -3 . The only chemistries with 95% confidence intervals ϾϮ1.0 ϫ 10 -3 g cm -3 were for NaNO 3 , NaHSO 4 , FeCl 2 , and K 2 CO 3 .…”
