初级中学化学课本及课外书籍中,有关气体溶解度(压强不变)随温度升高而减小的实验,大都采用冷水加热冒气泡的方法。为了开阔学生的视野,增强实验效果,我们特设计了以下两种不同的实验方法。供参考。
In junior high school chemistry textbooks and extracurricular books, experiments concerning the reduction of gas solubility (invariable pressure) with increasing temperature have mostly adopted the method of cold water heating and air bubbles. In order to broaden students’ horizons and enhance experimental results, we have specially designed the following two different experimental methods. for reference.
