初中化学教材中给出了一氧化碳还原氧化铜实验的两种装置 ,其一是用气球收集尾气 ,其二是点燃尾气。这两种装置中 ,由于玻璃管水平放置 ,生成的二氧化碳不易排出 ,从而阻碍一氧化碳与氧化铜接触 ,使得反应进行的时间较长 ,现象也不明显。结合木炭还原氧化铜、氢气还原氧化铜实 In junior high school chemistry textbooks, two devices for reducing copper oxide by carbon monoxide are given. One is to collect exhaust gas with a balloon, and the other is to ignite the exhaust gas. In both types of devices, due to the horizontal placement of the glass tubes, the generated carbon dioxide is not easily discharged, thereby impeding the contact of carbon monoxide with the copper oxide, and the reaction takes a long time and the phenomenon is not obvious. Combined with charcoal reduction of copper oxide, hydrogen reduction of copper oxide
