Interpretation:
The reason for the use of gravity filtration instead of suction filtration to remove the suspended impurities and charcoal from a hot solution should be explained.
Concept introduction:
Gravity filtration is the process that is used to separate the solids from liquids based on the particle size with the help of gravity. This method is used when the filtrate is to be retained and the residue on the filter paper is discarded. It is a slow process and removes only large particles from the air.
Suction filtration is a technique that is used to separate the mixtures of solids and liquids. This method is used when the solid is to be retained and the filtrate is discarded. It is much faster than gravity filtration.

- Vacuum filtration is just one method that can be used to separate the components of a mixture. Describe another method for separating the components of a mixture, and comment on how "green" the method is. Be sure to indicate the physical state of each component during separation. Scientific literature should be cited as part of your response.arrow_forwardA sample of fried potatoes weighing 200 g was extracted using a volatile organic solvent. The recovered cooking oil weighed 15 g. What methods from this experiment could be used to separate the cooking oil after the extraction? What was the percent oil in the potatoes? Show your calculations. How is gravity filtration different from vacuum filtration? Give examples of mixtures that can be separated by gravity filtration.arrow_forwardExplain the difference between constant rate filtration and constant pressure difference filtration using mathematics and examples.

- Weigh out accurately 9.99 g of copper(II) sulfate pentahydrate (CuSO4·5H2O) by taring using a clean and dry empty 250-ml beaker. 2. Add tap water to the beaker to reach the 50-mL mark on the side of the beaker. 3. Dissolve all the crystals of CuSO4·5H2O in the water using a clean glass rod for stirring. 4. Then using a glass funnel transfer all the blue solution to a 100-mL volumetric flask. Rinse the beaker with about 10 mL of water and transfer the solution to the volumetric flask. Repeat the rinsing of the beaker with another 10 mL of water and transfer the solution to the volumetric flask. This is called quantitative transfer of the solution. 5. Then add enough water to reach the calibration mark of the volumetric flask. (You will need to use a dropper to add the last few drops of water to ensure the meniscus is on the calibration mark). Close the volumetric flask with a stopper and mix the solution well (so that it is homogeneous). 6. You have now prepared a standard solution (or…arrow_forwardhow to use Gas Chromatography in Cosmetics Provide a procedure on how to do this example that you provided.
