教材中对氯气和氢气爆鸣实验的做法是先收集一瓶氯气和一瓶氢气,再把两瓶气体口对口对接,使其混合后再用镁条燃烧照射引爆。此方法有一定的弊端:成功率很低,易污染环境,药品消耗量大。我通过多年的教学实践,现将其进行改进。一、原理
Teaching materials on chlorine and hydrogen burst experiment approach is to first collect a bottle of chlorine and a bottle of hydrogen, and then two bottles of gas counterpart docking docking, and then mixed with magnesium burning combustion detonation. This method has some drawbacks: a low success rate, easy to pollute the environment, large drug consumption. Through years of teaching practice, I now improve it. First, the principle
