一、课本实验“氨分子扩散”的不足氨气有很难闻的刺激性气味,在完成该实验的过程中会给实验人员带来很大的不便,同时也会造成一定的环境污染。二、针对不足,提出改进措施在教师的指导下,我仔细分析了该实验存在不足的原因,并有针对性地提出了改进措施:1.由于氨分子会在实验过程中不断地扩散,所以该实验最好在密闭系统中进行。2.实验结束后,装置内还会存在一定量的氨气,应该设法让
First, the textbook experiment “Ammonia Diffusion” Insufficient ammonia has an unpleasant irritating odor, in the process of completing the experiment will give the experimental staff a great deal of inconvenience, but also cause a certain degree of environmental pollution . Second, to address the deficiencies, proposed improvement measures under the guidance of teachers, I carefully analyzed the reasons for the lack of the experiment, and made targeted improvements: 1. As ammonia molecules will continue to spread during the experiment, so The experiment is best performed in a closed system. 2. After the experiment is over, there will be a certain amount of ammonia inside the device.
