| Abstract: | Viscosities of three binary systems namely, ethylene glycol (EG)-water, ethylene glycol-dioxan and ethylene glycol-acetone have been measured at five different temperatures in between 303.15 K and 323.15 K by using Ostwald Viscometer. The values of excess viscosities ηE are negative over the entire range of composition in all the phases studied except EG-water system. The positive ηE values for polar EG-water system are due to the strong intermolecular H-bond with water. But negative ηE values in the other two non-polar (acetone is less polar) systems are probably due to inclusion of smaller EG molecule and less effective H-bonding. The ηE values have been fitted to highly composition dependent Redlich-Kister equation. |
