引言在滴定分析中,络合滴定法创立至今不过j十余年,由于它具有更多的优越性,所以已有巨大发展并广泛地应用于生产、科研和教学之中。但是,相对于其他几种滴定分析来说,它所涉及的理论和实际问题要复杂的多。如何从这个复杂体系中探讨其理论与实际的基本规律,就成为分析化学工作者们研究的课题之一。再从络合滴定法一章教材来看,其特点是常数。系教多,公式推导多,干扰因素多,在处理教材进行教学时,怎样突出重点,化繁为简,以便学生理解和掌握,也是应该讨论的问题。
INTRODUCTION In the titration analysis, the complexometric titration method has been established for more than ten years. Due to its superiority, it has been developed tremendously and widely used in production, research and teaching. However, the theoretical and practical issues involved are much more complex than the other titration analyzes. How to explore the basic laws of theory and practice from this complex system has become one of the topics studied by analytical chemistry workers. Then from the chapter titled complexometric titration materials, its characteristic is constant. It is also a problem that should be discussed when it comes to teaching more, deriving more formulas and more disturbing factors. When dealing with teaching materials, how to give prominence to emphasis and simplify the teaching so that students can understand and master it?
