Densities (ρ), viscosities (η), ultrasonic velocities (μ) and conductivities (κ) have been measured by using specific gravity bottle, Ostwald’s viscometer, single frequency ultrasonic interferometer (6 MHz frequency) and conductivity meter respectively for aqueous solutions of sodium chloride and potassium chloride at different concentrations (w/w). Various acoustical parameters viz. Adiabatic compressibility (βad), intermolecular free length (Lf), acoustical impedance (Z), relaxation time (τ), rao’s constant (RM), wada’s constant (W), free volume (Vf), absorption coefficient (α/f2), gibb’s free energy (ΔG), relative association (RA) and available volume (Va) were calculated from these experimental data. The results are interpreted in terms of molecular interactions between components of solutions.
