化学实验是化学科学研究的重要方法,也是化学教学的重要手段。在普通高中化学教材《化学反应原理》第二章“反应速率和化学平衡”第一节“化学反应速率”中,编者设计了锌与硫酸反应的演示实验,其基本原理是利用锌与不同浓度硫酸反应,产生相同体积气体所需时间的不同来测定化学反应的速率,希望通过该实验促进学生进一步理解化学反应速率的基本原理和思路,强调化学反应的速率是通
Chemistry experiment is an important method of chemical science research, but also an important method of chemistry teaching. In the ordinary high school chemistry textbook “chemical reaction principle” second chapter “reaction rate and chemical equilibrium ” section “chemical reaction rate ”, the editor of zinc and sulfuric acid reaction demonstration design experiment, the basic principle is to use Zinc and different concentrations of sulfuric acid reaction to produce the same volume of gas required to determine the difference between the rate of chemical reaction hope that through this experiment to promote students to further understand the basic principles of chemical reaction rate and ideas to emphasize the rate of chemical reaction through
