对分析化学中有关沉淀溶解度影响因素的补遗

The Addendum to the Factors Influencing the Sediment Solubility in Analytical Chemistry

《分析化学》教材在分析沉淀溶解度的影响因素时只考虑了有酸效应或有同离子效应时的影响,而对既有酸效应又有同离子效应时对沉淀溶解度的影响却没有涉及,这无疑是一疏漏。结合对《分析化学》教材的分析就这一遗漏进行了讨论,并通过相关例题的计算,对学生在什么情况下只考虑酸效应,或既要考虑酸效应又要考虑同离子效应时沉淀溶解度的影响,作出了较为清晰的解释。

The textbook ''Analytical Chemistry' only takes into account the influence of acid effect and ion effect in analyzing the factors influencing the sediment solubility, and it doesn't concern the influence of acid effect and ion effect on sediment solubility, which is no doubt a careless omission. Integrated with the analysis of 'Analytical Chemistry', the paper discusses this careless omission, and enables students to have a rather clear idea about when to take into consideration the acid effect only, and when to take into account the influence of both the acid effect and the ion effect on sediment solubility.
