目前分析化学实验教学中,还存在着一些需要研究和解决的问题。如定性分析实验中,学生根据离子性质做出正确判断感到困难,不能准确检出离子。在定量分析中,实验过程中的数据未能迅速及时处理,往往在实验结束后,写实验报告时才发现实验结果错误,需要重做。为提高实验教学质量,教师应及时处理学生的实验数据,指出实验中存在的问题,必要
At present, there are still some problems that need to be studied and solved in the analytical chemistry experiment teaching. Such as qualitative analysis experiments, students make the right judgments based on the nature of the difficulty, can not accurately detect ions. In the quantitative analysis, the data in the process of experiment can not be dealt with promptly and quickly. When the experiment report is written, it is often found that the experimental results are wrong and need to be redone. In order to improve the quality of experimental teaching, teachers should deal with students’ experimental data in time and point out the problems in the experiment.
