标准电极电位在化学上应用甚广,几乎从大学无机化学,高年级专门化课程一直到科学研究,无不应用它来解释某些问题,预测一些现象。但对多价元素,经常只列出几对电极电位数据,或实验只能测出这几对电位数据,因而必然会产生这样的问题:如何由一元素已知电对的标准电极电位,确定该元素未知电对的标准电位呢?本文即想介绍二种可用的方法。
The standard electrode potential is widely used in chemistry, almost from the university inorganic chemistry, advanced specialization courses until scientific research, all without exception to explain some of the problems, predict some phenomena. However, for multivalent elements, only a few pairs of electrode potential data are often listed or the experiment can only measure these several pairs of potential data, and thus inevitably lead to the question of how to determine the standard electrode potential of a known pair of an element This element is unknown to the standard electric potential? This article would like to introduce two available methods.
