摘要：
Ultrasonic speed (U) and density (rho) values for BaCl2 solutions are presented in 10%, 20%, and 30% glycol + water mixtures at 303.15 K. The thermo acoustic parameters like isentropic compressibility (beta(s)), isothermal compressibility (beta(T)) and coefficient of thermal expansion (alpha) have been calculated for different solutions. The experimental values of sound speed have been fitted on Ballou's and Hartmann's equation for nonlinearity parameters and the variation of these parameters with the concentrations of solute in different solutions has been discussed in the context of ion-solvent interactions.
