ABSTRACT

In this work, densities have been measured for glycine in aqueous solutions of (0.01, 0.02, 0.03, and 0.04) mol*kg 1 sulfanilamide, sulfanilic acid, and sulfosalicylic acid dihydrate at temperatures from (288.15 to 308.15) K, using vibrating tube digital densimeter. These solution densities were used to calculate the partial molar volume values at infinite dilution, V8, for the glycine. The calculated parameters are used to interpret the solute solute and solute solvent interactions and structure making/breaking ability of the amino acid in the given aqueous sulfa drug solution.
