Ultrasonic studies of molecular interactions of certain Zinc electrolytes in Poly (Ethylene Glycol)


The present investigation was carried out in order to explore the possible molecular interactions of various zinc electrolytes in polyethylene glycol. Measurement of ultrasonic velocity (u), density (ρ) and viscosity (ƞ) have been carried out for the various systems of zinc sulphate+ PEG, zinc acetate+ PEG and zinc nitrate+ PEG in different concentrations at 303K. From the experimental data acoustical parameters such as adiabatic compressibility (βa), acoustic impedance (z) and intermolecular free length (Lf) have been calculated. These parameters are used to interprete the molecular interactions in terms of ion-solvent, ion-ion and solute-solvent of the electrolytic solutions.
