Using the evaporating method, the solubility of barium nitrate was determined in various mixtures containing water and ethanol at 25.0 °C. The results show that the solubility of Ba(NO 3 ) 2 decreases when increasing mass percent of ethanol in the mixtures. This trend is along with decreasing the dielectric constant of “water+ethanol” mixture. Moreover, it can be concluded that the...
