一、提出问题氢氧化钠与二氧化碳反应是氢氧化钠的重要化学性质之一 ,教材对该反应只是直接给出结论 ,没有编排实验。因此 ,笔者将该问题设计成一次探究活动。首先要求每位同学都去找资料 ,结合自己已有的知识 ,设计出能证明氢氧化钠与二氧化碳反应的实验方案 ,方法越多越好 , I. PROBLEM PROBLEMS The reaction between sodium hydroxide and carbon dioxide is one of the important chemical properties of sodium hydroxide. The textbook simply gives a direct conclusion to the reaction, and there is no layout experiment. Therefore, the author designed this question as an inquiry activity. First of all, ask each student to look for information and combine their own knowledge to design an experimental program that can prove the reaction between sodium hydroxide and carbon dioxide. The more methods, the better.
