Effect of concentration on thermo acoustic and nonlinearity parameters (B/A) of barium chloride solutions in glycol-water mixtures at 303.15Â K

► Binary mixtures of barium chloride in methanol-water, ethanol-water, dioxane-water and glycol-water have been studied. ► Density and ultrasonic velocity have been measured at constant temperatures. ► Thermo acoustic parameter and nonlinearity parameters are calculated. ► The results are discussed in terms of ion-ion and ion-solvent interaction.
