氧化还原滴定是分析化学教学的基本内容之一。但氧化还原滴定的理论处理尚不如酸碱与络合滴定理论处理那样完善,有的问题还处于研讨之中。本文拟对氧化还原平衡处理方法中出现的两个新概念——电子活度与半反应平衡常数谈一谈看法,并对氧化还原平衡的图解法提出作者的建议。
Redox titration is one of the basic contents of analytical chemistry teaching. However, the theoretical treatment of redox titration is not as perfect as that of acid-base and complexometric titration, and some problems are still under discussion. This article intends to talk about the two new concepts that emerge in the redox equilibrium approach: the electron activity and the half-reaction equilibrium constant, and proposes the author’s suggestion for the redox equilibrium diagram.
