摘要
Systematic measurements of density and speed of sound of Creatinine Hydrochloride in aqueous and in aqueous solutions of 0.06 mol.kg(-1) NaCl/KCl and 0.1 mol.kg(-1) NaCl/KCl were carried out at T = (288.15-318.15) K within the concentration range of (0.03 to 0.1) mol.kg(-1). All the measurements were performed for density and speed of sound simultaneously on Anton Paar DSA 5000 M. The density (rho) and speed of sound (u) were employed to calculate the various derived parameters such as apparent molar volume of solute (V-phi), limiting apparent molar volume of solute (V-phi(0)) limiting apparent molar expansivity (E-phi(0)), thermal expansion coefficient (alpha*), isentropic compressibility (k(s)), apparent molar isentropic compressibility (K-s,K-phi), limiting apparent molar compressibility (K-s phi(0)). The trends of variation of experimental and computed parameters have been discussed in terms of hydrophilic-ionic group interactions and hydrophilic-hydrophilic interactions operative in the systems.
