【 摘 要 】

The effect of ethanol addition to aqueous semi saturated NaCl solutions on the super saturation was studied. The amount of precipitated salt was found to increase as the percent of added ethanol increased. The rates of formation of precipitate were calculated and found to increase with decrease of the weighted average of the solvents mixture dielectric constant,e, but levels out ate≈ 50. The solubility of salt was then connected with the dielectric constant and a zero solubility was observed ate= 35. A magnitude of super saturation was defined for the measurement of solubility.
