一、常用简易装置1.过滤器(图略)2.洗气瓶(图略)3.集气瓶如图(1).气体从a进入,从b流出,则为收集比空气重的气体(向上排气);反之,则为收集比空气轻的气体(向下排气)。4.量气装置如图(2)。5.缓冲瓶如图(3),此装置用于所制备的某种气体需做溶解实验(被某液体吸收)。在气体发生装置和吸收装置之间,接上此装置用以避免液体倒流入气体发生装置。 First, commonly used simple device 1. Filter (figure omitted) 2. Washing bottle (figure omitted) 3. Collection of gas bottles as shown in Figure (1). Gas enters from a and flows out from b, collecting gas heavier than air (Exhaust upwards); otherwise, collect lighter than air (downward exhaust). 4 gas device as shown in Figure (2). 5. Buffer bottle As shown in figure (3), this device is used for the preparation of a certain gas to be dissolved (by a liquid). Between the gas generating device and the absorbing device, this device is connected to prevent the liquid from flowing back into the gas generating device.
