The thermodynamic measurement of 2-hydroxy substituted chalcone dibromide in a different solvents like ethanol, 1,4-dioxane and carbontetrachloride. Density and viscosity measurements were carried out in 0.01 M solution in different solvents at different temperatures. The viscometric measurements were done with the help of Ostwald's viscometer. The data so obtained were analyzed by using Jones-Dole equation. This study helps to predict the molecular interaction in solution mixture. The present study deals with the determination of the thermodynamic parameters such as Gibbs free energy change (??G), enthalpy change (??H) and entropy change (??S).
