摘要
在大学化学类课程教学中,返滴定分析计算历来是教学难点之一,学生很难掌握该项知识点。本文介绍一种利用等物质的量规则进行返滴定分析计算的方法,借助形象化的过程图示,可以帮助学生很好地进行返滴定分析计算。
In the teaching of chemistry courses in colleges and universities, analysis and calculation of back titration has always been one of the difficult points in teaching, and it is difficult for students to master this knowledge point. This paper introduces a method of analysis and calculation of back titration by using the rule of equal amount of substance. With the help of visualization process diagram, students can carry out analysis and calculation of back titration very well.
