Acoustical Study of Chalcone in Dmso – Water Mixture in Different Concentrtions

Abstract

Ultrasonic velocity and density measurement of chalcone - 3-bromo-2-hydroxy-5-methyl-4-chloro chalcone (3B2H5M4C1C) in dmso-water mixture have been carried out in the concentration range 1x10^-2 - 5x10^-2 mole dm^-3 and in different percentages of dmso-water mixtures. The experimental data have been used to calculate various acoustical parameters, such as adiabatic compressibility (β_s), apparent molal volume(ϕ_v), apparent molal compressibility(ϕ_k(s)), intermolecular free length (L_f), specific acoustic impedence (Z_s) and relative association (R_A). The results have been interpreted in terms of solute-solvent and solute-solute interactions.
