氯气是一种重要的化工原料,也是高中化学课程中重要的物质之一。但是由于氯气有毒不适合在教室做演示实验。大多数学校通常通过观看相关视频来介绍有关氯气的知识。对此,改进氯气制取及验证性质的实验后,可以将实验带进教室,从而加深学生对实验的认识。
Chlorine is an important chemical raw material and one of the most important substances in high school chemistry courses. However, due to toxic chlorine is not suitable for demonstration in the classroom experiment. Most schools usually introduce chlorine-related knowledge by watching the video. In this regard, to improve the nature of the chlorine preparation and verification of the experiment, the experiment can be brought into the classroom, thereby deepening students’ understanding of the experiment.
