两个直角玻璃导管 ,一个双孔塞和一个广口瓶 (或烧瓶、锥形瓶、试管等 )就可以组成洗气装置 ,如图 1。此装置在中学化学实验设计中有着广泛的应用。图 1 洗气瓶装置ａ .用于气体的净化。混有杂质的气体从ａ口进入 ,从ｂ口排出。如 :二氧化碳气体中混有少量氯化氢气体 ,就可使
Two right-angle glass tubes, a double-hole plug and a wide-mouth bottle (or flask, Erlenmeyer flask, test tube, etc.) can be used to form a gas scrubbing device, as shown in Figure 1. This device has a wide range of applications in the design of middle school chemistry experiments. Figure 1 Washing bottle device a. For gas purification. Gas mixed with impurities enters from port a and exits port b. Such as: carbon dioxide gas mixed with a small amount of hydrogen chloride gas, can make
