Acoustic behavior of electrolytes in aqueous dimethyl sulphoxide as a solvent at different temperatures

The density (d), ultrasonic velocity (U), and viscosity (η) have been measured for the electrolytes, i.e., potassium chromate, sodium chromate, and sodium thiosulphate in an aqueous solution of dimethyl sulphoxide (DMSO) solution at 293 K, 298 K, 303 K, 308 K, and 313 K. By using the measured data, the other parameters like adiabatic compressibility (β), relative change in adiabatic compressibility (Δβ/β),change in adiabatic compressibility (Δβ),apparent molal volume (Ø_v), apparent molal compressibility (Ø_k),intermolecular free length (L_r), specific acoustic impedance (Z), limiting apparent molal compressibility ( \(\emptyset_{\text{k}}^{0}\) ${\mathrm{\varnothing }}_{\text{k}}^0$ ), limiting apparent molkal volume (Ø _v ⁰ ) and their constants (S_k, S_v) can be calculated. The results obtained from the above parameters are helpful to determine the solute–solute and solute–solvent interaction.
