一、在实验中的运用1.喷泉实验原理:利用某种气体易被一种液体吸收而形成压强差,把液体压入烧瓶,在尖嘴处形成喷泉。例:在如图装置中,烧瓶中充满干燥气体a,将滴管中的液体b挤入烧瓶中,轻轻振荡烧瓶,然后打开f,a中形成喷泉,b液体几乎充满烧瓶,则a和b符合要求的是 First, the use of the experiment 1. Fountain experimental principle: the use of a certain gas is easily absorbed by a liquid to form a pressure difference, the liquid pressure into the flask, the formation of a fountain at the tip. Example: In the device as shown in the figure, the flask is filled with dry gas a, and the liquid b in the dropper is squeezed into the flask, the flask is gently shaken, and then f is opened, a fountain is formed in a, b liquid is almost filled with the flask, a and b is in line with the requirements
