Year: 2025
Type: article
Abstract: The hydration behavior and structural fittings of 5- Sulphosalicylic Acid + aqueous-(0.025, 0.050, 0.100) mol·kg-1KCl/CuCl2 solutions were studied by volumetric, acoustical and optical properties form measured densities and ultrasonic velocities at 303.15 K and 101 kPa. Partial molar volumes and compressibilities of 5- Sulphosalicylic Acid in aqueous-KCl/CuCl2 solutions were determined. In addition to this, the refractive indices of studied systems were measured. Significant changes in partial molar volumes and compressions of 5- Sulphosalicylic Acid were observed in presence of KCl/CuCl2. The measured and derived properties were interpreted in terms of ion-ion and ion-dipole in studied solutions. Volumetric, acoustical and optical properties indicated significant effect on hydration structure of 5- Sulphosalicylic Acid in regard with molecular interactions.
