The density (d), ultrasonic velocity (U) and viscosity (?) measurements have been carried out for strong electrolytes, e.g., magnesium chloride and zinc chloride in 5, 10 and 15 wt% of aqueous ethanol in different concentrations over the temperature range 298.15K to 313.15K at 5K interval. Various thermo-acoustical parameters, such as free volume (Vf), internal pressure (πi), relaxation time (τ), Gibb's free energy change (ΔG), ultrasonic attenuation (α/f2) and van der Walls constant (b) have been computed from the experimental data to investigate the ion-solvent and solvent-solvent interactions in these systems. The variation of these parameters has been discussed and interpreted in the light of molecular interaction and hydrogen bonding in the solutions.
