氨的催化氧化作用是中学化学实验中难度较大的一个实验。热心的同行纷纷提出了很多改进的方法,但在所有的改进实验中,不是装置繁杂,就是现象不明显。本文寻找到一种操作简单、现象明显、成功率极高的实验方法。一、实验仪器和药品铁架台,试管,平底烧瓶,酒精灯,带导管胶塞,石棉绒(或玻璃丝)。 The catalytic oxidation of ammonia is a more difficult experiment in middle school chemistry experiments. Enthusiastic colleagues have put forward many methods for improvement, but in all the improvement experiments, the device is not complicated, or the phenomenon is not obvious. This article has found an experimental method with simple operation, obvious phenomena, and high success rate. First, experimental equipment and medicines iron stand Taiwan, test tubes, flat-bottomed flasks, alcohol lamps, with catheter rubber plugs, asbestos velvet (or glass fiber).
