一、原实验存在的问题人教社大纲版第二册第13页图1—17为实验室制取氨气装置示意图,这是典型的在加热条件下固体与固体反应制取气体的实验装置。实验结果表明,该装置所得到的氨气湿度大,此为其一不足;其二,多余的氨气逸散到大气中污染环境,师生深受其害,故此装置亟待改进。 First, the existing problems in the experiment PEP outline book second volume Page 13 Figure 1-17 Ammonia plant for the laboratory schematic diagram, which is typical under heating conditions solid and solid reaction of the gas from the experimental device . Experimental results show that the ammonia vapor obtained by the device has a high humidity, which is an insufficiency. Second, excess ammonia gas is released into the atmosphere to pollute the environment, and teachers and students suffer. Therefore, the device is in urgent need of improvement.
