“氨的催化氧化”实验难度较大,不易做好。我们经过多次实验,摸索出一些实验方法。从效果看,实验现象明显,操作手续简便,时间只需2～3分钟。一、装置图二、实验准备 1.配制氨水。锥形瓶内的氨水,浓度为 The “catalytic oxidation of ammonia” experiment is difficult and difficult to do well. After many experiments, we explored some experimental methods. From the effect point of view, the experimental phenomenon is obvious, the operation procedures are simple and the time only takes 2 to 3 minutes. First, the device diagram 2, experimental preparation 1. Preparation of ammonia. Ammonia in conical flasks at a concentration of
