用贮气装置贮存气体进行化学实验,具有使用方便、气流速度可控、节约制气药品、气体使用完全等优点,所以贮气装置是中学化学实验中常用的装置。目前中学化学实验室配备的两种贮气装置,排气时有些麻烦———需不断地加水或鼓气。为了克服上面两种产品仪器的缺点,我利用常见的材
The gas storage device is used to store gas for chemical experiments. It has the advantages of convenient use, controllable gas flow rate, saving of gas-generating drugs, and complete use of gas. Therefore, the gas storage device is commonly used in middle school chemical experiments. At present, there are two kinds of gas storage devices that are equipped in the middle school chemical laboratories. They are troublesome when they are exhausted. They need to constantly add water or gas. In order to overcome the shortcomings of the above two product instruments, I use common materials
