| 摘 要： | G·Schwarzenbach等人在他们提出的过量金属离子中和曲线法中引入了表观离解常数(K_t、K_f、K_s)。笔者认为该常数包含着实际并不为常数的游离金属离子浓度项(M]),因而概念不够严密,亦使计算复杂化。本文提出了该实验的新的数据处理方法。其处理结果与文献方法一致而物理意义更为明确。

| Abstract: | G. Schwarzenbac et al. used superficial dissociation constants in pH-Titration method with the metallic ion in excess proposed by themselves. The present authors think that these constants comprise free metallic ion concentration which is not a constant in fact and thus do not have clear physical meaning and make calculation complicated. A new data-treatment method for the experiment of pH-Titration method with the metallic ion in excess is presented in this paper. The result is in agreement with that of literature and the physical meaning is clear. |
