Research on Ion-Solvent Interactions in the Inorganic Liquid Mixtures by Ultrasonic Technique

Abstract

Ultrasonic speed, density and viscosity of binary liquid mixtures of aqueous ammonium per sulphate with other sulphate solutions at 303.15 K have been measured. From these experimental data, the adiabatic compressibility, intermolecular free length, internal pressure, acoustic impedance, relaxation time, molar volume, classical absorption coefficient and surface tension have been computed. The excess viscosity, excess compressibility, excess intermolecular free length, excess acoustic impedance and excess molar volume values are evaluated to find the nature and the extent of the interactions between the constituent molecules of the liquid mixture systems
