在分析化学基础课的教学中,络合滴定是很重要的一章,而混合离子的滴定又是该章的主要内容之一。在这部分内容的教学中,既要用到分析化学最基本的原理,又要教会同学用正确而简便的方法去思考和处理一些比较复杂的问题,因此,教材内容是相当重要的。但是我 In the teaching of analytical chemistry basic course, complexometric titration is a very important chapter, and titration of mixed ions is one of the main contents of this chapter. In this part of the content of teaching, it is necessary to use the most basic principles of analytical chemistry, but also to teach students to use the correct and easy way to think about and deal with some of the more complex issues, the textbook content is very important. but I
