Abstract: The present experimental investigation was carried out in order to explore the possible thermodynamic and interactions studies of D(+) fructose with mixed solvent of aqueous alkali metal halides at different molalities and constant temperature . Experimental values of densities and ultrasonic velocities were carried out of the ternary mixture solution D(+)fructose with aqueous NaCl ,KCl , MgCl2 and CaCl2 under different molalities and at 303K. The related and relevant parameters correlated to the present study such as adiabatic compressibility Ks, acoustic impedance Z, apparent molal volume фv, apparent molal adiabatic compressibility, фKs, and partial molal volume ф0v and partial molal adiabatic compressibility, ф0Ks at infinite dilution. The present investigation has exploited the possible molecular associations such as ion-ion, ion-solvent, interactions in these systems. It has been observed that there exist strong solute-solvent interaction and complex formation between in these ternary systems.Abstract: The present experimental investigation was carried out in order to explore the possible thermodynamic and interactions studies of D(+) fructose with mixed solvent of aqueous alkali metal halides at different molalities and constant temperature .

Abstract: Densities and viscosities of Glycine in aqueous NaCl and MgCl2(0.02& 0.06 M ) solutions have been determined experimentally at 30oC.The results obtained from density and viscosity measurement have been used to calculate A and B coefficients and free energies of activation of viscous flow of solvent Δ µ10# and solute Δ µ20# .The results are discussed in terms of the dehydration effect of the electrolytes upon the amino acids and weak solute- solute and strong solute- solvent interactions. The properties of these amino acids in water and water+ electrolytes solution systems are discussed in terms of the charge , size and hydrogen bonding effect.Abstract: Densities and viscosities of Glycine in aqueous NaCl and MgCl2(0.02& 0.06 M ) solutions have been determined experimentally at 30oC.The results obtained from density and viscosity measurement have been used to calculate A and B coefficients and free energies of activation of viscous flow of solvent Δ µ10# and solute Δ µ20# .The results are dis...Show More
