Investigation Of Ultrasonic Velocity And Related Acoustical Parameters Of N–(2- Hydroxybenzylidene)-3-Substituted Pyridine-2-Amine Schiff Base Derivatives In Ethanol-Water Mixture At 293, 297 And 300 K

The density, viscosity and ultrasonic velocity of synthesized Schiff base N – (2- hydroxybenzylidene) pyridine-2-amine and its substituted derivatives have been studied in ethanol-water mixture at 293, 297 and 300 K over a wide range of concentration. From these experimental data, various acoustic parameters like apparent molar compressibility , specific acoustic impedance (Z) and relative association (RA) have been evaluated. The results are interpreted in terms of molecular interactions like solvent-solvent, solvent-solute and solute-solute interactions.
