Apparent molar volume and coefficients of Jones-Dole equation for the evaluation of ion-solvent interactions of barium chloride in aqueous 1, 4-dioxane and ethylene glycol solutions at T= (298.15 K to 313.15) K and at atmospheric pressure

The viscosity and density of barium chloride have been measured at T= (298.15-313.15) K in aqueous solutions of 1, 4-Dioxane (1,4-DO) and Ethylene glycol (EG). Jones-Dole equation was used to analyze the viscosity data. The apparent molar volume. V-phi limiting apparent molar volume, .V-phi(0) are calculated from the density data. Limiting apparent molar expansibilities. E-phi(0) have been used to describe the temperture dependency of V-phi(0). The standard volume of transfer, Delta V-t(phi)0 and viscosity B-coefficient of transfer, Delta B-t of barium chloride from water to aqueous 1, 4-DO and EG solutions were systematizing the different types of interactions in the given solutions. The structure making and breaking capacity of solute in solutions was interpreted with the help of Helper equation. The positive value of (partial derivative V-2(phi)0/partial derivative T-2)(p) suggests the structure making nature for BaCl2 in given solution. It is observed that Friedman-Krishnan co-sphere model explains the increase in the transfer volume of BaCl2 with an increase in 1,4-DO and EG concentrations. The activation parameters of the viscous flow of the given solutions were calculated and interpreted using transition state theory.
