ABSTRACT
Ultrasonic velocity (u), density, and viscosity have been measured for glycylglycine and CoCl2 in aqueous and aqueous ethanol systems at T = (288.15 to 318.15) K. Using the experimental values, the adiabatic compressibility , molar hydration number, apparent molar compressibility, apparent molar volume, limiting apparent molar compressibility, limiting apparent molar volume, their constants (SK, SV), viscosity coefficients of A and B parameters of Jones-Dole equation, relative viscosity, and excess Gibbs free energy of activation were calculated and the results of all these parameters have been discussed in terms of solute-solvent and solute-solute interactions.
