摘要
＂量＂的概念是分析化学中的重要概念。对滴定分析实验中学生在＂量＂的概念上存在的一些问题的进行了分析。结合教学实践,从理论教学、实验数据的记录与处理、正确选择实验仪器、规范实验操作等方面提出了在滴定分析实验教学中树立正确的＂量＂的概念的措施。
Abstract
Concept of quantity was an important concept in analytical chemistry.Some existing problems of the concept of quantity in the experiment of titration analysis were analyzed.Combined with the teaching practice,from the theoretical teaching,experimental data recording and processing,correct choice of experimental apparatus and experimental operation,some measures were presented in titration analysis experimental teaching to establish a correct concept of quantity.
