在基础分析化学教学中是否有必要引入滴定曲线方程?各家看法不一。国内外绝大多数分析化学教材不提及这个问题,只有少数几本教材讲述了这个问题。笔者从七九年起即在基础分析化学教学中向学生讲授滴定曲线方程以及从滴定曲线方程推导滴定误差。三年来教学实践证明,这样讲授是有好处的,它能使学生对整个滴定分析形成一个比较系统和比较完整的概念,教学前呼后应,学生也很容易掌握,并且学生掌握滴定误差计算时不必另起炉灶从头教起,而从滴定曲线方程很快就可推出滴定误差公式,一举两得。最近,国内也推荐了这种教学方式。
Is it necessary to introduce a titration curve equation in basic analytical chemistry teaching? The vast majority of analytical chemistry textbooks at home and abroad do not mention this issue, only a few of the teaching materials about this issue. From 1979, I taught titration curve equations to students in basic analytical chemistry teaching and derived titration errors from titration curve equations. Three years of teaching practice has proved that such teaching is beneficial, it enables students to analyze the entire titration to form a more systematic and relatively complete concept, teaching before and after the call should be easy for students to master, and students grasp the titration error calculation You do not have to start from scratch and start teaching from the titration curve equation titration error formula can be introduced quickly. Recently, this kind of teaching method is also recommended in China.
