Study of Acoustic Properties of Luminol in DMSO-Water Mixture

The acoustical properties like adiabatic compressibility (s), apparent molal volume (v), apparent molal compressibility (k), intermolecular free length (Lf), specific acoustic impedance (Z) and relative association (RA) of Luminol have been calculated from measured sound velocities (U) and densities (r) of their solutions of 0.01M concentrations in different percentage of DMSO-water mixture at 298.15 K. The variations in acoustical properties with increasing percentage of DMSO have been used tounderstand the changes in molecular interactions between water, DMSO and Luminol and to know the structure making and breaking property of solvent molecules on addition of DMSO in presence of Luminol.
