“一氧化碳还原氧化铜”实验的一体化设计

Integrated Design of the Experiment of “Reduction of Copper Oxide by Carbon Monoxide”

借助物质相互转化的原理,仅在一支试管中设计了一氧化碳还原氧化铜的实验;改进后的实验利用传感器收集实验数据,培养学生严谨的证据意识;从气体制备到尾气的处理,创新实验均体现绿色化学的观念。该实验的一体化设计,药品用量少,操作简单,实验耗时短,现象明显,提高了学生的参与度,提升了实验教学效果。

With the principle of mutual transformation of matter, the experiment of reduction of copper oxide by carbon monoxide was designed in only one test tube. Sensors were used to collect data of improved experiment to train rigorous consciousness of evidence for students. From the gas preparation to the treatment of exhaust gases all reflected the concept of green chemistry. The integrated design of experiment, less drug consumption, simple operation, short time, and obvious phenomena, improved the participation of students and elevated the teaching effect remarkably.
