The interaction parameters Ax and Bx were calculated using modified Jones-Dole equation. The three concentration region in HClO4-H2O system were obtained which have been confirmed from kinetic data. To show the influence of interaction parameter on reaction rate, the hydrolysis of methyl acetate catalyzed by perchloric acid has been performed. The study is an illustrative model in the advancement of solution chemistry.
