化学实验是化学学科的基石。CO2的性质与制法是九年级化学中的一个重要章节,知识点多,重难点多。虽然在教材中安排了较多的实验来帮助学生理解和掌握知识点,但在实际教学中,仍然有一些重要的教学内容只能停留在教师的口头讲述上,而无法通过实验进行验证。传感器技术的引入,给我们带来了功能强大的探究实验工具,使一些传统实验无法实现或不能直观呈现的科学探究有了实现的可能。CO2能溶于水,广大教育工作者对实验室能否用 Chemistry experiments are the cornerstone of chemistry. The nature and preparation of CO2 is an important chapter in the ninth grade chemistry. There are many points of knowledge and heavy and difficult points. Although more experiments are arranged in the textbook to help students understand and master the knowledge points, there are still some important teaching contents in the actual teaching that can only stay on verbal narration of teachers and can not be verified through experiments. The introduction of sensor technology has brought us a powerful tool for research and exploration, making it impossible for some scientific experiments that can not be achieved or can be visualized by traditional experiments. CO2 can dissolve in water, the majority of educators on the laboratory can use
