Ultrasonic study of molecular Interactionsof binary liquid Mixtures and polymer solutions

Abstract

Ultrasonic velocity density and other acoustical parameters have newlinebeen carried out for the aqueous solutions of ammonium chloride with newlineammonium sulphate ammonium oxalate with ammonium formate and zinc newlinenitrate with zinc sulphate in water at different concentrations at a frequency of newline2 MHz at 303 K Using the ultrasonic velocity and density adiabatic newlineCompressibility intermolecular free length acoustic impedance molar newlinevolume and other parameters have been calculated The graph between newlinevelocity and mole fraction of ammonium sulphate in the mixed salt solution newlineshows a dip and a complex at a composition of 60 40 Similar newlinenon linear variations are observed in the mixed solution of ammonium oxalate newlinewith ammonium formate solution It shows a dip at a mole fraction of 0 8181 newlineof ammonium oxalate The same non linear variations occurred in the mixed newlinesalt solution of zinc sulphate and zinc nitrate All the other acoustic newlineparameters have been calculated The value of velocity decreases and comes newlineto a minimum and then increases with concentration Velocity shows dip at newlinethe composition of 20 80 The results are interpreted as per the intermolecular newlineinteraction newline newline
