Abstract

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