  • Abstract

    Ultrasonic velocity, density and viscosity of monochloroacetic acid (MCAA) solutions in 10, 20, 30, 40, 50, 60, 70, 80, 90 and 100 wt. % isopropanol-water have been determined at 298.15,303.15 and 308.15 K. Viscosity and density data of these solutions were analysed with John-doles and Masson`s equation. The viscosity coefficient A and B, the limiting apparent molar Volume (Φ0v) and experimental slop (SK), ultrasonic velocity (U) and derived parameters namely, adiabatic compressibility (βad), apparent molar compressibility (Φk), intermolecular free length (Lf), specific acoustic impedance (Z) and salvation number (Sn) throw light on solute-solvent and solute- solute interactions. Consequence of temperature disparity on these interactions is discussed.
