The density and speed of sound for glycols (EG, DEG, and TEG) in an aqueous solution of D-Mannitol have been measured by Anton Paar DSA 5000M at different temperatures and concentrations. Experimentally obtained data of density and speed of sound are employed to calculate various theoretical parameters such as intermolecular free length, acoustic impedance, adiabatic compressibility, Wada’s constant, Rao’s Constant, and Vander Waal’s constant which gave the better insight into molecular interactions between the glycols and D-mannitol solutions. The linear trend for all the parameters implies the absence of complex formation in the system.
