华中师院等三校编写的《分析化学实验》我们已经使用四届了。这本书从整体上看,逻辑性强,内容有更新,便于教学。但在实践中发现个别地方还需要改进,以便于学生掌握。本文根据几年来所做的大量实验和研究,对实验教学中第二组与第三组阳离子分离时调节酸度的问题和铜锡组分离后cd~(2+)的分离与鉴定的方法问题,提出如下改进意见: Central China Normal University and other three schools written in “Analytical Chemistry Experiment” We have used four. This book as a whole, the logic is strong, the content is updated, easy to teach. However, in practice, we find that some places still need to be improved so that students can grasp it. In this paper, based on a large number of experiments and research done over the past few years, the problem of adjusting the acidity of the second and third groups of cations in the experimental teaching and the separation and identification of the cd ~ (2+) after the separation of the copper- Put forward the following improvements:
