Abstract

Density, refractive index and ultrasonic velocity of sulphosalicylic acid with concentration range (0.02, 0.04, 0.06, 0.08 and 0.1) mole·kg-1 in aqueous (0.025, 0.050 and 0.100) mol∙kg-1 solutions of d-mannose have been measured at T= 303.15 K. The effects of concentration of dmannose on different thermodynamic properties such as density, refractive index and ultrasonic velocity have been calculated. Derived thermodynamic properties such as apparent molar volume ( 2, V ), partial molar volume (  o V2 ), isentropic compressibility ( s K ), apparent molar isentropic compressibility (   S,2, ), partial molar compressibility ( 0 ,2,  S ) specific acoustic impedance ( z ) and atomic polarization ( a P ) are calculated by using measured properties. These properties have been explored in terms of molecular interaction between solute and cosolute
