氢气爆鸣实验的方法很多,本文选择操作简单安全,现象明显,仪器易得的八种方法。通过氢气爆鸣实验的不同设计,培养学生的创新意识,激发学生学习化学的兴趣。一、取一个一端开口,另一端钻有小孔的可乐杯或纸筒,用小纸团堵住小孔。用向下排空气法收集氢气,收集满后,移开氢气发生装置,拿掉小纸团并用燃着的木条在小孔处点燃。可以看到,刚点燃时氢气能安静 There are many hydrogen burst test methods, this article choose simple and safe operation, the phenomenon is obvious, the instrument is easy to get eight methods. Through different designs of hydrogen burst experiment, students’ innovative awareness is stimulated, and students are encouraged to learn chemistry. First, take one end of the opening, the other end of a small hole drilled coke cup or paper tube, with a small paper lumps blocking the hole. Collect hydrogen with the downward air method. After the collection is over, remove the hydrogen generator, remove the small pieces of paper and ignite the small holes with the burning pieces of wood. It can be seen that hydrogen can be quiet just after it is ignited
