课本上的两个演示实验——氯化氢和氨气的“喷泉”实验是高中阶段最重要也是对学生最具吸引力的两个基本实验.要做好“喷泉”实验很容易,但要分析清其中所含的原理并不容易,它渗透着物理和化学学科的综合知识.随着高 The two demonstration experiments in the textbook—the “Fountain” experiment of hydrogen chloride and ammonia are the two most important experiments that are most important for the high school students and are most attractive to students. It is easy to do a “Fountain” experiment, but it is necessary to analyze The principle contained in it is not easy, it permeates the comprehensive knowledge of physics and chemistry. With high
