Patnaik 1 Department of Chemistry, Utkal Universtiy, Bhubaneswar, Orisha (INDIA) <p style="text-align: justify;">Various acoustic parameters such as isentropic compressibility (b_s), intermolecular free length (L<em>_f</em>), apparent molar volume (f), apparent molar compressibility (f<em>_k</em>), molar compressibility (<em>w</em>), molar sound velocity (<em>R</em>),acoustic impedance (<em>z</em>) of Na₂SO₄ in 10%, 20% and 30% methanol+water at303.15 K have been determined from ultrasonic velocity (<em>V</em>), density (r) and relative viscosity (h<em>_r</em>) of the solution. These parameters are related with the molar concentration of the solution and reflects distortion of the structure of the solvent (<em>i.e</em>., Propan-2-ol+water) when the solute is added to it.</p> https://journalofchemistry.org/paper/745/ Ultrasonic studies Propan-2ol+water solvent
