新编化学教材燃烧与灭火中,继白磷在空气中燃烧的演示实验之后,接着演示白磷在水中燃烧实验。教材上实验装置和操作虽然都很简单,但演示过程中却费时费力,现象极不明显,影响了教学效果。在新编教材教学的当年,带着这个问题,我在实验室对此进行了研究。导致实验不成功的原因很简 In the new chemistry textbook Combustion and Fire Extinguishing, following the demonstration experiment of white phosphorus burning in air, the white phosphorus burning experiment in water was then demonstrated. Although the experimental devices and operations on the teaching materials are very simple, the demonstration process is time-consuming and laborious. The phenomenon is extremely insignificant and affects the teaching results. In the year of the new textbook teaching, with this question, I conducted research in the laboratory. The reason for the unsuccessful experiment is very simple
