Small chemistry problem Within the scope of high school chemistry experiments,Filtration is mainly used to separate aqueous solutions and crystals that precipitate or precipitate,The second unit of high school chemistry has a lecture,You can have a look.1.2.1.A beaker for dumping liquid,2.3.Applicable object of extraction,For example,Separation of Bromo in water with benzene,It is more soluble in benzene,So that the Bromo ran from the water into benzene,Benzene is almost insoluble in water,The solution is layered.Now that it's layered,Next to the liquid,In the experiment,Extraction and liquid separation are generally carried out together,So there is no need to talk about the object applicable to the liquid separation.Through this example,It is known that the applicable object of extraction liquid separation is generally an aqueous solution with a large difference in solubility in organic solvents (benzene, carbon monoxide, etc.High school does not require extraction operations,These operations are
