Organic Chem Lab Midterm Flashcards | Quizlet

    Organic Chem Lab Midterm. Gravity filtration is used to remove suspended impurities from a hot solution. This is so, because if vacuum filtration is used, the lower pressure of the suction flask would cause the filtrate to boil. If this happened, the material in solution would be deposited over the walls of the flask.

    What Do Carbon Filters Remove From Water? | Livestrong

    Types of Carbon Filters. However, there are many factors that affect this rate, including the amount of carbon in the unit, the flow of water, the length of time contaminants spend in contact with the carbon and the particle size. Carbon can remove particles 50 micrometers to 0.5 micrometers in size.
