Study of Solute-Solvent Interaction of Some Pesticide-Monochrotophos with Aqueous Organic Sovlents

Abstract

Ultrasonic velocity, density and viscosity measurements have been used to calculate isentropic compressibility (

bs), intermolecular freef), ultrasound velocity (V), density (r), excess viscosity (h), specific acoustic impedance (Z), Rao's constant (R), Shear's relaxationts), apparent molal adiabatic compressibility (xk) and excess values (AE) of solutions of pesticides-monochrotophos in aqueousbs) intermolecularf), density (r) and viscosity increases with the increases in molar concentration of monochrotophos. As usual apparent molalxk) has been found to be negative in both cases. The results have been interpreted in terms of ion-solvent
