Study of Molecular Interactions in Aqueous 2-Amino-5-Nitrothiazole-NiCl2 Solution at Different Temperatures and Concentrations

Thakare AR and Naik AB

Ultrasonic velocity and density of aqueous 2-amino-5-nitrothiazole – NiCl2 solution was guarded at different temperatures (303.15 K, 308.15 K, 313.15 K and 318.15 K) and concentrations, so as to know about the molecular interaction between solute and solvent. In these studies acoustical parameters such as intermolecular free length, isentropic compressibility, specific acoustic impedance, relative association and ultrasonic velocity number were used to interpret types of molecular interactions present in the aqueous 2-amino-5-nitrothiazole -NiCl2 solution of different concentrations at different temperatures. Measured values indicate the presence of effective correlation in the form of solute - solvent interactions and metal-ligand interactions for different concentration and temperature.
