Bonding Effect

Densities, ultrasonic velocities and viscosities of L- Valine and L- Phenylalanine in aqueous sodium bromide (0.00, 0.025 and 0.05) m solutions have been determined experimentally at 308 and 313 K. The results obtained from density ultrasonic velocity and viscosity measurement have been used to calculate the apparent molal volume, фv, apparent molal, adiabatic compressibility ф Ks, partial molal volume ф0v at infinite dilution, partial molal adiabatic compressibility ф0Ks at infinite dilution, transfer volume ∆ф(tr), experimental slopes Sv and SKs,Falkenhagen coefficient A and  Jones-Dole B coefficient. The results are discussed in terms of the dehydration effect of the sodium bromide upon the amino acids and weak solute- solute and strong solute- solvent interactions. The properties of these amino acids in water and water + sodium bromide solution systems are discussed in terms of the charge, size and hydrogen bonding effect.

Equivalent Conductance

The conductances, densities, and viscosities of sodium chlorate and of lithium chlorate in the solvents 44.5% dioxane–55.5% water and 64.5% dioxane–35.5% water were determined, at 25 °C, almost up to saturation. The apparent molal volume of the electrolytes, calculated from the density data, was found to be greater in the dioxane–water solvents than it is in water, indicating a decrease in solvation in the mixed solvents. The relative viscosity increased as the dioxane content of the solvent increased, showing a larger ordering effect of the electrolytes as the solvent became less hydrogen bonded and less ordered. The equivalent conductance of both electrolytes was greatly reduced as the dioxane content of the solvent was increased, in accord with predictions based on solvent viscosity and dielectric properties. Also, sodium chlorate was found to be more associated than lithium chlorate in the mixed solvents.

Apparent Molal Compressibility

In this study binary and ternary solutions are prepared by using the sodium acetate concentrations (0.1, 0.125, 0.2, 0.25, 0.4, 0.5, 0.8, 1 M) in water and acetone –water mixtures .The important parameters such as apparent molal volume, the partial molal volume transfer,  apparent  molal compressibility, free energy of activation of viscous flow and thermodynamic activation parameter (enthalpy and entropy) determined of sodium acetate in water , 20%, 40% ,60% and 80% V/V acetone –water mixtures at 298.15K, 303.15K, and 308.15K from density and viscosity measurements espectively. The limiting apparent molal volumes and experimental slopes were derived from the Masson equation, have been interpreted in terms of solute–solvent and solute–solute interactions  respectively. The viscosity data were analyzed using theJones–Dole equation and the derived parameter B - coefficient has also been interpreted in terms of solute–solvent interactions in the solutions.
