摘要
实验教学中,参照《分析化学实验》[1](下称《教材》)所述方法配制的Mg2+-EDTA标准溶液在放置过程中产生了沉淀,经查阅同类文献[2-4],没有该相关知识的介绍,本文研究了此问题并提出了解决方法,可避免由此而引发的教学疏漏和实践中化验结果的错误.
The experimental teaching,with reference to "Analytical Chemistry Experiment"[1](here in after referred to as "materials") method described in the preparation of the Mg2+-EDTA standard solution in place of the deposition process,with access to similar literature,there is no knowledge of the introduction.In this paper,this problem and proposed solution to avoid this omission caused by the teaching and practice of the wrong test results.
