高中化学第一册第六章第三节的演示实验（６－２），氨跟氯化氢起反应实验。在课堂演示操作过程中，较麻烦，实验现象不够明显，易造成失败，而且酸和氨的液体易沿着玻璃棒下淌，造成公物和环境的污染。为此，在实践过程中，通过多次摸索、思考和实际操作演示，可将此演示实验 The demonstration experiment (Section 6-2) of Chapter 6 of Section 3 of High School Chemistry Book 1, ammonia reacts with hydrogen chloride. In the classroom demonstration operation, it is more troublesome, the experimental phenomenon is not obvious enough, and it is easy to cause failure. Moreover, the liquids of acid and ammonia tend to squat along the glass rod, causing public and environmental pollution. For this purpose, in the course of practice, this demonstration experiment can be conducted through multiple explorations, thoughts, and practical demonstrations.
