ABSTRACT

Precise density and viscosity measurements on aqueous solutions of lithium acetate, sodium acetate, potassium acetate, magnesium acetate, and calcium acetate have been carried out in the temperature range of T ) (288.15 to 318.15) K using a vibrating-tube digital densimeter and Micro-Ubbelohde type capillary viscometer, respectively. The data have been used to obtain partial molar volumes at infinite dilution, V2 o, and viscosity B-coefficients for these salts. The effect of temperature on these thermodynamic properties has been studied by determining the partial molar expansibilities ( YV2 o/ YT)P and ( Y2V2 o/ YT2)P and ( YB/ YT) coefficients. The activation free energies, cents E2 0,+, for the viscous flow of solutions have also been obtained by application of transition state theory to the viscosity B-coefficient data. The results have been rationalized in terms of various interactions taking place in these solutions.
