Ultrasonic Velocity, Density and Viscosity Studies in the Aqueous Solutions of Hydrate Compounds

Ultrasonic velocity, density and viscosity have been measured in the aqueous solutions of three hydrates levofloxacin hemihydrate, tacrolimus monohydrate and lisinoprildihydrate at two temperatures 30 and 40 0 C. Apparent molar volumes and apparent molar compressibilities have been computed and the limiting/partial molar volumes and molar compressibilities have been discussed in the light of solute-solvent / solute-solute interactions. Jones Dole constants A and B have also been computed and in turn employed to assess the molecular interactions. Mostly solute-solvent interactions dominate in the aqueous solutions. Also from Jacobson’s theory of
