混合理想气体的分压定律是基础无机化学教学中的一个重要定律,也是历年来教学中的一个难点。为此,我们设计了一个简单易行的课堂演示实验,既可以巩固和运用理想气体状态方程和波义耳定律,又可以近似地验证混合理想气体的分压定律。实践证明,收到了良好的教学效果。

The law of partial pressure mixing ideal gas is an important law in the teaching of basic inorganic chemistry, and it is also a difficult point in teaching in the past years. For this reason, we designed a simple and easy classroom demonstration experiment, which can consolidate and apply the ideal gas state equation and Boyle’s law, and can also verify the partial pressure law of the mixture of ideal gases approximately. Practice has proved that it has received good teaching results.
