今介绍三种化学实验中常用的贮气装置如下。第一种,装置如图一。贮气容器A是一只1000毫升的白小口瓶。(用白大口瓶更好,但瓶塞难配)。用一只500毫升的聚乙烯瓶B作为长颈漏斗,(也可用250毫升的分液漏斗代替。)贮气时先使A中盛满水,将气体经导气管通入,将A中的水压入B。(当B中液面太高时要设法移去一些水,以免溢出。)需要用气时,只要打开导气管,气体便能送出。(B中的
Now introduced three kinds of chemical experiments commonly used gas storage device is as follows. The first, the device shown in Figure one. Gas storage container A is a 1000 ml white small mouth bottle. (Better with a white jar, but difficult to match the stopper). A 500 ml polyethylene bottle B was used as a long neck funnel (alternatively, a 250 ml separatory funnel was used instead.) A was filled with water while the gas was being stored and the gas was passed through an airway tube. The Water pressure into B. (Try to remove some water when level is too high in B to avoid spilling.) When gas is needed, the gas can be delivered by simply opening the airway. (B in the
