近代化学发展初期,人们已经就熟知用氢还原氧化铜(Ⅱ)或氧化亚铜(I)的实验,而且通过这个实验来理解化学变化中的定量关系。然而这个实验用氢作还原剂存在一些问题和不足的地方: 实验装置设备相对说来复杂了一些,也易于引起爆炸事故。因此在操作中必须注意安全。为此,过去曾经有许多人尝试探索用其它还原剂,如丙烷或城市用的煤气来代替氢,实验结果表明,还不如氢理想。日本的大石博、白崎三千年两位作
In the early days of modern chemical development, people were already familiar with experiments using hydrogen to reduce copper oxide (II) or cuprous oxide (I), and through this experiment to understand the quantitative relationship in chemical changes. However, there are some problems and deficiencies in the use of hydrogen as a reductant in this experiment: The experimental equipment is relatively complicated and can easily cause explosions. Therefore, care must be taken during operation. To this end, many people have tried to explore the use of other reducing agents such as propane or city gas instead of hydrogen. The experimental results show that it is not as good as hydrogen. Japan’s Dashibo and Baizaki made two thousand years.
