Study of the Thermodynamic Parameters by the Dissolution of Barium Hydroxide in Water through Conductivity Method

Abstract

Syed A Ali, Muhammad Z Iqbal, Atya Hassan

The dissolution of Barium hydroxide (Ba(OH)2) in pure water was used for finding out its thermodynamic parameters by conductivity method. The effect of ionic salts as well as the influence of some mixed solvent (1,2-propanediol and ethanol) were also studied. It was found that the added ionic salts produced fewer changes in the thermodynamic parameters compared to mixed solvents. Moreover, the combined salts and mixed solvent system collectively changed the thermodynamic parameters more differently as compared to the separate systems. These results were compared with the dielectric constant and ionic strength of the media.
