Viscosity and Density of Ternary Solution of Calcium Chloride plus Sodium Chloride plus Water from T = (293.15 to 323.15) K

Viscosities and densities of ternary systems of CaCl2-NaCl-water were measured in the range of T = (293.15 to 323.15) K at 5 K intervals and up to 4.5 mol.kg(-1). Two equations based on the Exponential and Goldsack and Franchetto models were applied to correlate the experimental viscosity data as a function of concentration and temperature. The optimized parameters showed that the presence of CaCl2 had a prevailing effect on the viscosity of the ternary solutions than NaCl. The dependency of the viscosity optimized parameters on temperature was investigated, too. The average absolute deviation between calculated and experimental viscosities was below 1.4 %. The work compared the above-mentioned two models to the known extended Jones Dole equation and found that both models do correlate the viscosity at higher concentrations better than the Jones Dole equation. However, the exponential model shows the superior representation for the experimental viscosity values over the other two Density data were successfully predicted with an average absolute deviation of less than 0.45 96. studied models.
