A.Ringbon采用了“副反应系数”、“条件稳定常数”概念来处理复杂的络合平衡体系,使复杂的计算得以简化。本文采用了类似方法,用“副反应系数”、“条数件溶度积”来处理复杂的溶解平衡。目前计算难溶物质的溶解度一般采用解联立方程或用分布系数概念导出的公式。国内的教科书中虽引入了“副反应系数”概念,但未应用于溶解度的计算。国外虽有用“副反应系数”来计算的,但没有一个较为简便的计算通式。本文引入了副反应系数δ、条件溶度积K_(SP)′、导出了溶解平衡计算的简便通式,列举了计算实例。
A. Ringbon uses the concepts of “side reaction coefficient” and “conditional stability constant” to handle complex complex equilibrium systems, simplifying complex calculations. In this paper, a similar method is used to deal with the complex dissolution balance by using “side reaction coefficients” and “number of pieces of solubility product”. The current calculation of the solubility of insoluble substances generally uses the solution equations for solving the solution or the formula derived from the concept of distribution coefficients. Although domestic textbooks introduce the concept of “side-reaction coefficients,” they have not been used to calculate solubility. Although foreign countries use the “side-reaction coefficient” to calculate, but there is no one more simple formula. In this paper, the side reaction coefficient δ and the conditional solubility product K_(SP)’ are introduced, and a simple formula for the calculation of the dissolution equilibrium is derived. The calculation examples are listed.
