Abstract

Ultrasonic investigations are carried out in aqueous solutions of organic dyes, methyl violet, and methlene blue to study the behavior of these dyes in aqueous binary mixtures formed with methanol, formamide, and dimethyl formamide as solutes in a water-rich region. The sound velocities are evaluated using a single crystal variable path interferometer working at 1 MHz with an accuracy of +/- 0.003%. The densities are measured using a Pycnometer and velocities with an Ostwald's viscometer. The various acoustical and thermodynamic parameters are evaluated using experimental solutions. An attempt has also been made to evaluate the excess thermodynamic functions like excess molar volume and excess compressibility in the binary mixtures and hence study the nature of molecular interactions of the dye compounds with different interactions the dye compounds on water structure in presence of different solutes in a water-rich region.
