| 摘 要： | 对高中化学第一册中“铜与浓硫酸反应”演示实验的实验装置和实验方法进行了改进，用可移动的铜丝代替铜片，并对硫酸的浓度进行了探索。结果表明，当硫酸的浓度为80％时，实验现象鲜明，反应时问短，教学效果明显。

| Abstract: | There are many insufficiencies in the demonstration experiment of copper reaction with concentrated sulfuric acid in Book one of chemistry course in senior high school. By improving experimental method and experimental device,if we use moveable copper sheet instead of brass wires,and explored the concentration of sulfuric acid in this experiment,the results showed that when the conncentrtion of sulfuric acid was 80%,the experimental phenomenon was more obvious,the reaction time was shorter and the teaching ... |
