配位滴定中副反应处理方法的区别与联系

在现有的教科书中，有关配位滴定中副反应处理方法有两种，即副反应系数法和副反应分数法。这两种方法以简明的数学方法解决了配位滴定中的复杂平衡关系。但是对于这两种方法之间的联系尚未明确，从而给教师的讲授以及学生的学习带来不便。为此本以副反应系数法和副反应分数法基本理论的建立为依据，通过比较和讨论明确了两的联系，从而使教与学的进程更为顺畅。

The Connection and Differences between Two Methods Used to illustrate Side Reactions in Complexometric Titration

The side reaction coefficients and distribution ratios are usually used to illustrate side reactions in complexometric titration. With them we can solve the difficult complex equilibrium problems. It is necessary for students who study analytical chemistry to understand the connection and difference between the side reaction coefficients and distribution ratios if they want to use them correctly. But no paper for this purpose has been seen. So we make a careful examination of relation between two methods, in the belief that it would be helpful to the teaching and study of complexometric titration
