ChemInform Abstract: A STUDY OF SOLUTE-SOLVENT INTERACTION IN SOLVENTS OF MEDIUM DIELECTRIC CONSTANT FROM THE APPARENT MOLAL VOLUME DATA PART 1

Ultrasonic velocity (U), viscocity (η) and density (ρ) ofL- ascorbic acid, dextrose and sucrose in aqueous guanidine hydrochloride (0.3 m) have been measured at 298.15 K. The derived acoustical parameters namely adiabatic compressibility (β), apparent molal compressibility (ΨK) apparent molal volume (ΨV) limiting apparent molal compressibility (Ψ0K) limiting apparent molal volume (Ψ0V) and their constants (SK, Sv) and viscosityB- coefficient and hydration number (nH) have been computed from the experimental data. The variation of these parameters with respect to the molality of solutes have been explained on the basis of solute-solvent interaction and structure making tendency of the solutes in solvents.

Apparent Molal Adiabatic Compressibility

The present experimental investigation was carried out in order to explore the possible molecular interactions of D(+) mannose with mixed solvent of aqueous NaCl, KCl , MgCl2and CaCl2at 303 K. Experimental values of densities and ultrasonic velocities were carried out of the ternary mixture solution D(+) mannose with aqueous NaCl ,KCl, MgCl2and CaCl2. Aqueous alkali metal halides (NaCl ,KCl , MgCl2and CaCl2) were added under different molalities with D(+) mannose. 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 ф0vand partial molal adiabatic compressibility, фoKsat infinite dilution. The present investigation has exploited the possible molecular associations such as ion-ion, ion-solvent, solute-solute and solute-solvent interactions in these systems. It has been observed that there exist strong solute-solvent interaction and complex formation between in these ternary systems.

Apparent Molal Compressibility

Acoustical and volumetric properties have been measured for substituted heterocyclic compounds digoxin and thiabendazole in 1, 4 dioxane at 303 K. The ultrasonic velocity measurement have been performed to evaluate acoustical parameter such as adiabatic compressibility (βs), partial molal volume (ɸv), intermolecular free length (Lf), apparent molal compressibility (ɸk), specific acoustic impedance (Z), relative association (RA), salvation number (Sn), limiting apparent molal compressibility (ɸ0k), limiting apparent molal volume(ɸ0v) and their constant (Sk,Sv). The viscosity coefficient (A, B) was evaluated by using john–dole equation. These parameters throw the light on the solute-solvent interaction and solute-solute interaction.
