Ultrasonic and Volumetric Studies of Aqueous Solution of Polyethylene Glycol

Abstract

In present study an attempt has been made to analyse the molecular interactions of aqueous solution of polyethylene glycol of molecular weight 200 at different concentration and at different temperature by determining density, viscosity, and ultrasonic velocity. Various parameters like, adiabatic compressibility acoustic impedance and intermolecular free length have been calculated at different temperatures and at 0.50% concentration. This study helps to understand the physio-chemical behavior of macro molecules with change in temperature and concentration.
