Acoustical Study of Chalcone in Dioxane: Water Mixture in Different Concentrations

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 (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.
