چکیده انگلیسی
The effects of temperature, pressure, and concentration on viscosity of aqueous LiI solutions were determined with a capillary-flow technique and compared with literature data and correlations. The data are interpreted with the extended Jones-Dole equation for strong electrolytes to calculate the viscosity A-, B-, and D-coefficients. Good agreement was found between derived values of the viscosity A- and B-coefficients and the results predicted by Falkenhagen-Dole theory of electrolyte solutions and calculated with the ionic B-coefficient data. It was found that the temperature coefficient, dB/dTÂ >Â 0, for LiI(aq) is positive (structure-breaking ions). Physical meaning parameters V and E in the absolute-rate theory of viscosity and hydrodynamic molar volume Vk were calculated using present experimental viscosity data. The values of parameter E almost independent on temperature (around 11.1), while the values of parameter V monotonically decreasing as temperature increases. The Arrhenius-Andrade parameters (A and Ea/R) were calculated from measured viscosity data. The predicted capability and validity of the various theoretical models for the viscosity of electrolyte solutions were tested.
