Description
Summary:Ultrasonic velocity and density of four ternary liquid systems have been determined experimentally at 298.15 K. All the four ternary systems comprise of a polar molecule, viz., chlorobenzene or chloronapthalene (first component) and a mixture of two alkanes (second and third component) consisting of different size and shapes. Excess molar volume has been calculated and these values along with the other computed parameters, viz., K S E, K T E, u E, Δ V and δ u have also been computed. The main aim of the present investigation is to study the influence of a polar molecule in terms of size, shape and polarity to a mixture of hydrocarbons (binary) on the experimental and thermodynamic excess properties.
