对于氯气和氢气光化爆鸣实验,很多老师反映不易做成功,影响了学生的学习兴趣和课堂教学效果。过去曾有一些化学教师对此实验进行了改进,获得了较好的效果。但这些改进多是把氯气和氧气的制取装置和爆鸣装置联结在一起。这样做,不但使本来简单的爆鸣实验复杂化,增加了四十五分钟之内的教学负 For chlorine and hydrogen photon burst experiments, many teachers report that they are not easy to succeed, affecting students’ interest in learning and classroom teaching. In the past, some chemistry teachers have improved this experiment and achieved good results. However, these improvements are mostly linked to chlorine and oxygen production devices and sounding devices. This will not only complicate the simple explosion experiments, but also increase the teaching load within forty-five minutes.
