| Abstract: | The Clegg-Pitzer semi-empirical thermodynamic equations were applied to the calculation of 1-1 type potassium salt aqueous solution.At 25 ℃ and over the whole concentration range,from 8 single -electrolyte solutions (KF,KCl,KBr,KI,KOH,KNO3,KClO3,KBrO3),the parameters WH２O,KX,UH２O,KX,and BKX were calculated,and then 8 solubility products were calculated.From 9 bi-salt saturated aqueous solutions,the parameters WKXY,UXY,and QH２O,KXY were regressed,the F-test was passed. |
