ABSTRACT

Volumetric and acoustic study of sucrose with ammonium phosphate salts viz. ammonium dihydrogen phosphate (ADP) and diammonium hydrogen phosphate (DAP) has been done using an oscillating U-tube instrument namely Anton-Paar DSA 5000M. Densities and speeds of sound in aqueous solutions of sucrose and mixed aqueous solutions of (0.0, 0.5, 1.0 and 1.5) mol*kg-1 ADP and DAP have been measured at four different temperatures (288.15, 298.15, 308.15, 318.15) K and experimental pressure p = 0.1 MPa. Making use of the density and speed of sound data, the respective apparent molar volume ( V ) and apparent molar isentropic compression ( K ,s ) in aqueous solutions of sucrose and mixed aqueous solutions of ADP and DAP have been determined at the above four temperatures.
