摘要
大气中含有21%的氧气,高中化学中常出现制造无氧环境来排除氧气对实验干扰的实验探究。有人提出了利用有机溶剂隔离空气实现无氧环境的方法,但对其可行性未进行详细分析。从溶解理论和实验验证的角度进行了研究,证实了有机溶剂不可隔离氧气制造无氧环境。
The atmosphere contains 21% oxygen,the inquiry experiment of creating an oxygen-free environment to eliminate the interference of oxygen often appear in high school chemistry teaching.Some people put forward the method of isolation of oxygen by organic solvent,this article conducted the research from the dissolution theory and experiment,confirmed that the organic solvent could not isolate oxygen.
