Thermo Acoustical Characterization of Several Inorganic Salts in Polyvinyl Pyrrolidone at 303.15 K, 308.15 K, 313.15 K

Abstract

Abstract The ultrasonic velocity, density and viscosity values of liquid mixture of aqueous polyvinyl pyrrolidone with aqueous zinc sulphate, manganese sulphate, zinc chloride and manganese chloride have been studied at 303.15 K, 308.15 K and 313.15 K. Relative association, surface tension, modified surface tension, adiabatic compressibility, acoustic impedance, intermolecular free length relaxation time and the nonlinearity parameter have been determined for various compositions. The variation observed in the results suggest that the presence of strong polymer-solvent interactions.
