Densities and Speeds of Sound for Sucrose in Aqueous Solutions of Ammonium Phosphate Salts at Different Temperatures through Density and Speed of Sound Measurements
Volumetric and acoustic studies of sucrose with ammonium phosphate salts, namely, ammonium dihydrogen phosphate (ADP) and diammonium hydrogen phosphate (DAP), have been carried out using an oscillating U-tube instrument, namely, Anton Paar DSA 5000 M. 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, and 318.15) K and an experimental pressure of p = 0.1 MPa. Making use of the density and speed of sound data, the respective apparent molar volume (V-phi) and apparent molar isentropic compression (K-phi,K-s) in aqueous solutions of sucrose and mixed aqueous solutions of ADP and DAP have been determined at the above four temperatures.
