摘要
作者使用计算机解一元弱酸溶液中氢离子浓度的精确方程，得出ｐＨ－ｐＣ和Ｒ－ｐＣ曲线，揭示了离解度极限值的规律，对溶液“无限稀释”的概念提供了定量的依据，为描述弱酸离解平衡提供了图示法，并从计算和作图上证明了－元弱酸稀释过程中氢离子浓度单调变小．
This article has solved the precise equation of the hydrogenous ion concentrations in a monobasic weak acid solution,and also got the curves of the pH-pC and R-pC by means o f computer lrevealed the law of limit of the dissociation degreefsuggested a quantitative criterion for the concept of the 'solution infinite diluting'lprovided a schematic diagram for discribing the dissociation equilib.ria of the weak acid solution.
