摘要:

对于复杂酸碱溶液体系,在处理和推导其质子平衡条件式时具有一定的难度。本文以FeCl3水溶液为模型,从三种平衡关系式出发,多角度、系统地讨论了体系中质子平衡条件式的处理和推导结果,并采取不同的方式对质子平衡条件式进行了验证,进一步深入探讨了溶液酸碱平衡体系的基础理论。

Abstract:

For complex acid-base solution system, it is difficult to deal with the proton equilibrium condition and deduce its proton balance equation (PBE). In this paper, taking FeCl3 aqueous solution as a model, we discuss the treatment for proton equilibrium condition, and deduce systematically the proton balance equations based on various equilibrium relations in acid-base solution. These derivation results of PBE have been verified by different methods.

Key words: Analytical chemistry, Acid-base equilibrium, Proton balance equation, Mathematical derivation, FeCl3
