STUDY OF ACOUSTICAL PARAMETERS OF MONOMETHYLAMMONIUM PERCHLORATE IN SOME NON-AQUEOUS SOLVENTS AT DIFFERENT TEMPERATURES USING ULTRASONIC TECHNIQUE

Ultrasonic velocity and density for monomethylammonium perchlorate (CH3NH3ClO4) in non-aqueous solvents Dimethylsulfoxide (DMSO), N, N-Dimethylacetamide (DMA) and Acetonitrile (AN) were measured as a function of molality at temperatures 298K, 308K, 318K and 328K using DSA 5000M (Anton Paar density and sound velocity meter). Using this data, various acoustical parameters like adiabatic compressibility (Ks), apparent molal volume (VΦ), specific acoustic impedance (Z), intermolecular free lengths (Lf) and relative association (RA) have been determined. The variation of the acoustical parameters studied with molal concentration is then explored to understand the fundamental picture of various intermolecular interactions taking place.
