金属钠燃烧实验在高中化学教学中占有重要地位,但在实验过程中,现有的实验装备、实验器材、实验条件并不能够很好地向同学们展示金属钠燃烧的实验现象,难以实现教学目标和实验要求.1金属钠燃烧实验现象当进行金属钠燃烧实验时,学生往往只能看到一些黑色的物质,而没有看到其他的,诸如淡黄色过氧
Sodium metal combustion experiment occupies an important position in high school chemistry teaching. However, during the experiment, the existing experimental equipment, experimental equipment and experimental conditions are not able to show students the experimental phenomenon of sodium metal combustion, and it is difficult to realize the teaching Objectives and Requirements of Experiments.1 The Phenomenon of Sodium Metal Burning Experiments When performing sodium metal burning experiments, students often saw only a few black substances without noticing others, such as light yellow peroxygen
