一、问题的提出氯化氢的实验涉及气体的制取和性质实验,可以用于教学中的演示实验,也可以让学生在实验室中制取,锻炼其实验技能。但是实验中存在以下一些问题:1.教材中的装置无法进行整体性的气密性检查。2.氯化氢气体在收集时易扩散,会对空气造成污染,而且影响接下来的喷泉实验效果。 First, the question raised Hydrogen chloride experiments involving gas production and nature of the experiment can be used in teaching demonstration experiments, but also allow students to take in the laboratory, exercise their experimental skills. However, there are some problems in the experiment as follows: 1. The device in the teaching material can not conduct integral air tightness inspection. 2. Hydrogen chloride gas is easy to diffuse during collection, it will pollute the air and affect the next fountain experiment.
