摘　　要：针对氯气有毒及其与金属反应易于泄露等实验不足，设计了氯气制取、氯气与金属反应和氯水成分探究的全封闭实验。其中，氯气与金属的反应采用原位电加热的方式，加热速度快，金属在氯气中的燃烧现象明显，且能快速识别产物，有效地消除了因加热带来的氯气泄露问题；氯水成分的探究是通过青霉素瓶在封闭条件下进行的。整个实验仪器常规，装置简单，药品用量少，操作容易，现象明显，安全无污染，非常适合课堂演示。According to the toxicity of chlorine and the leakage in the reaction between metal and chlorine, this paper designed the completely airtight experiment including the preparation of chlorine, the reactions between metals and chlorine and the inquiry of chlorine water. In the ex- periment, the metal was heated via electric current in situ to react with chlorine, which could im- prove heating speed, resulted in the intense burning of metal wires and convenient recognition of products. Probing the composition of chlorine water could be carried out in a sealed bottle. This experiment was very suitable for classroom demonstration based on the following advantages： in- struments were conventional and simple, the amount of reagents was small, easily to be operated with obvious phenomena and green.
