以量筒和橡皮塞來設計一具有簡易、安全及快速功能之氣體製備裝置,以供作一些常用氣體如氫氣、氧氣、二氧化碳、一氧化氮、二氧化氮及二氧化硫等六種氣體之製備與檢驗,所排出來的液體經收集後可再重複使用,以節省藥品。
A simple, safe and rapid technique has been designed and developed with a graduated cylinder and some small materials for the purposes of the preparation and identification of some gases such as H_2, O_2, CO_2, NO, NO_2 and SO_2. After each experiment, the reactants can be recovered and reused, therefore, the amounts of consumed chemicals may be minimized in chemical experiments.
