The Improvement of Experimental Devices and Methods on Phosphorous

本文将“无机化学实验”中几个有关磷的实验装置及方法进行了改进 ,采用封闭装置 ,避免了原实验过程污染环境的缺点 ,并可对实验产物进行鉴定与利用 ,经多次重复实验 ,效果较好 ,达到了教学目的。

In this paper,several experiment devices and methods on phosphorous were improved.By using sealed devices,the environmental pollutions in the original experiment were avoided.The products could be identified and used in following experiment.Repeated experiments indicated that good results can be achieved,as is the teaching aim.
