| Abstract | The physicochemical properties provide detailed information about the effect of solvent on structural changes insolutions. These properties are explained in terms of ion-solute or solute-solvent interactions. The density and viscosity of thepolymer solution were measured at 303 K, 308 K, 313 K, 318 K and 323 K for 1% concentration of dextran. Ultrasound speed(U) in the solution was also measured at the four frequencies 1MHz, 5MHz, 9MHz, and 12MHz. Acoustic parameters such asadiabatic compressibility (ฮฒ), acoustic impedance (Z), relaxation time (ฯ), intermolecular free length (Lf), and Gibbs energy (ฮ"G),were also computed for these 1% dextran polymer solutions. These data are intended for analyses of the solvent-solvent, solvention, and ion-ion interactions. |
