摘　　要：氨气的制备及性质验证实验是中学化学最常见和极具趣味性的实验,而传统的实验装置,在实验过程中容易造成氨气的外逸,存在操作繁琐、浪费时间及尾气处理不彻底的问题。针对传统实验装置存在的不足,对实验装置做了改进,形成制取氨气和性质验证的一体化实验装置,缩短了实验时间,简化了实验过程,实验现象明显,符合实验微型化要求和绿色化学的理念。The preparation and verification of ammonia is one of the most common and interesting experiments in secondary school chemistry.However,the traditional experimental apparatus,which is prone to the escape of ammonia gas,is cumbersome,time-consuming and has the treatment problem of incomplete exhaust gas.In order to address the shortcomings of the traditional experimental apparatus,the present experimental apparatus has been improved to form an integrated one for ammonia production and property verification,which shortens the experimental time,simplifies the experimental process and makes the experimental phenomenon obvious,in line with the requirements of experimental miniaturization and the concept of green chemistry.
