Renu Loshali, Bhuwan Chandra and Neeti Sah And Narain D. Kandpal

In the present study, we have investigated the in teractions of hydrochlor ic acid in concentrated aqueous solution in the concentration range 1.0 to 8.0 moldm − 3 at 297.65 K viscometrically. The viscosity parameters have been calculated from Jones-Dole equation, modified Jones-Dole equation, Grunberg- Nissan equation and Hind equation. The trends of variations in B-coefficient have been explained in three concentration regions in hydrochloric acid-water system. The existence of all the three regions have been confirmed from kinetic results for the catalyzed hydrol ysis of the ester in aqueous solution by the acid. The study is useful for the advancement of solution chemistry.
