摘　　要：将基础化学实验可视化,可以让学生看见化学反应过程,提高学生学习兴趣,是一个值得研究的课题。以五水硫酸铜的制备和结晶过程为例,让学生利用智能手机拍摄实验过程,实现实验的可视化。本实验主要通过控制变量法探究影响产品产率的硫酸浓度、硝酸浓度和反应温度等因素,学生自己拍摄硫酸铜结晶的实验过程,并分享心得,从而将注意力集中到实验课堂,提高了课堂参与度。这个过程可以增强化学实验的感染力,也让学生直观地感受到化学反应过程的美丽和乐趣,可为基础化学实验的教学注入新的活力。Visualizing the basic chemistry experiment can allow students to see the chemical reaction process and increase their interest in learning. It is a topic worth studying. During the preparation and crystallization process of copper sulfate pentahydrate, students are asked to use smart phones to photograph the experimental process to realize the visualization of the experiment. This experiment mainly explores factors such as sulfuric acid concentration, nitric acid concentration and reaction temperature that affect the product yield through the control variable method. The students themselves photograph the experimental process of copper sulfate crystallization and share their experiences, thus focusing their attention on the experimental classroom and improving the classroom participation. This process can enhance the appeal of chemical experiments, and also let students intuitively feel the beauty and fun of the chemical reaction process, which can inject new vitality into the teaching of basic chemistry experiments.
