笔者认为，现行中师及高中《化学》必修第一册的氯化氢和氨的喷泉实验装置结构复杂，制气困难。若连续几班或隔天上同一节课，制的气体很难保存。且实验对烧瓶干燥程度要求高，滴管内排水量很难掌握，实验成功率较低。为了克服上述问题，现改进如下： 一、实验装置图 二、实 The author believes that the existing hydrogen chloride and ammonia fountain experimental device in the first division of the “Master Chemistry” and “High School Chemistry” compulsory volume is complex and difficult to produce gas. If a few classes or the same class every other day, the system gas is difficult to save. And the experiment has high requirements for the degree of drying of the flask, it is difficult to grasp the discharge volume within the dropper, and the experimental success rate is low. In order to overcome the above problems, the improvements are as follows: I. Experimental setup II.
