“…(9) Parameters q 1 to q 20 were determined by a weighted least-squares fit of equations (6), (7), (9), (10), and (11) to the experimental results (446 points) from tables 1 and 2. The equations were optimized by repeated least-squares regression in order to eliminate redundant parameters that were not significant at the 95 per cent confidence (6) ; (16) q, Goldsack and Franchetto; (17) r, Allred and Woolley; (18) W, Dunn; (14) R, Wirth; (12) T, Redlich and Bigeleisen; (13) 8, Äkerlo¨f and Teare; (11) y, Herrington et al; (20) u, Hershey et al (19) (b), 373 K E T E 573 K: w, present results at p = 10 MPa; r, present results at p = 28 MPa.…”

“…Many researcher has adapted a model based on absolute rate theory derived by Goldsack and Frachetto 23 to predict the viscosity of electrolyte mixtures 42 , 43 . The equation is as follows: X 1 and X 2 are the mole fractions presented in the following two equations for a solution made of two electrolyte 1 and 2, while E and V are dimensionless free energy and volume parameters, subscript 1 and 2 are for the corresponding binary solutions.…”

Measured viscosity and density data for ternary aqueous solutions of CaCl2 and KCl are presented at temperatures between 293 and 323 K with 5 K increment. A modified Jones–Dole was introduced by adding extra terms and proved to be suitable for modelling of the viscosity data. Goldsack and Franchetto, Hu and Exponential models are used to correlate the viscosity data, too. Al models are correlated as a function of temperature and concentration. All models had successfully predicted the viscosity with high precision reaching a maximum average absolute deviation (AAD) of less than 2.3%. The modified Jones–Dole showed the best results among other models. Viscosity of the ternary solution is higher than the viscosity of water by about 15% at low concentrations and reaches about 270% at the highest concentrations. The amount of CaCl2 has more significant effect on the ternary mixture viscosity compared to KCl. This has created difficulty in measuring the viscosity and consequently the challenge in finding the different models parameters. Ternary solution densities were successfully correlate with Kumar’s model with AAD of less than 0.4%. Comparison of the ternary solution density and viscosity with the few available data literature showed a good agreement.

“…Equation (4.2) is widely used for explaining viscosity data in many electrolyte solutions. Many attempts have been made to develop the theories and equations to establish an unique relation between viscosity η r and concentration c, applicable to the whole concentration region, not only for a single salt solution but also for mixed electrolyte solutions [40][41][42][43][44][45]. In this endeavour, it is found that an empirical relation with the inclusion of one additional term, Ec 3.5 , is reasonably good in explaining viscosity data of many electrolytes over the full concentration range [46].…”

The nature of variations of ultrasonic wave velocity( ) and attenuation constant(α) with the concentration(c) in aqueous solutions of NaCl, KCl and CsCl are investigated at room temperature(25 0 C) at 1MHz and 2 MHz wave frequency. Fourier Spectrum Pulse-Echo (FSPE) technique is used to achieve better accuracy in measurement, particularly for α measurement. In NaCl and KCl abrupt changes in the values of and α are noticed at particular solution concentrations whereas, for CsCl almost smooth variation in is observed over the whole concentration range for both of the frequencies 1 and 2 MHz . The nature of variation in and α in these solutions are analyzed in view of other spectroscopic studies. The well-known Jones-Dole equation that explains the viscosity(η) variation in many electrolyte solutions, offers satisfactory fits to the experimental velocity variation with parameter values characteristics of the sample.
