氢气和氯气的混合气体在日光或在镁带燃烧所产生的短波光线照射下 ,会发生爆炸反应 ,生成氯化氢。为了演示这一反应 ,原《高级中学课本化学 (必修 )第一册》(1 995年 1 0月版 )教材第 5面中采用了两套装置 ,一套制备收集氯气 ,一套制备收集氢气 ,涉及仪器药品多 ,操作繁琐。改 The mixture of hydrogen and chlorine gas will react in the sunlight or short-wave light generated by the combustion of the magnesium belt, and an explosive reaction will occur to generate hydrogen chloride. In order to demonstrate this reaction, the original “Senior Middle School Textbook Chemistry (Compulsory) Volume 1” (October 1, 995) was used on the 5th side of the textbook. Two sets of devices were used to prepare a collection of chlorine gas and a set of hydrogen for preparation. Involving many instruments and drugs, tedious operation. change
