统编教材高中第一册氯气一节,演示实验要分六步进行,且在教师演示实验的过程中,不可避免地有氯气溢出,这样既耗费时间又严重地污染环境,使师生受到一定的毒害。为此,我们把六步实验综合于一体克服了上述弊端,改装后的装置如附图所示。 The textbook edited the first section of the chlorine content in the first volume of the high school textbook. The demonstration experiment was divided into six steps. In the process of the teacher demonstrating the experiment, chlorine gas inevitably spilled. This wastes time and seriously pollutes the environment, causing teachers and students to suffer certain problems. Poisoning. For this reason, we integrated the six-step experiment into one to overcome the above drawbacks, and the modified device is shown in the drawing.
