Unit 4 M1 Filter Paper
Task 1 M1 Describe the scientific principles behind each of the three procedure above. Vacuum filtration is a procedure when a sold needs separating from a solvent to react the mixture. Then the mixture of a solid is measured through the filtration paper in a Buhner funnel. The liquid is drained through the funnel into the flask. Equipment • Filter paper • Buhner funnel • Tubing • Clean solvent • Disposable dropper Method 1. When carrying out this scientific technique you first need filter paper, tubing, clean solvent, and disposable dropper. 2. Clamp the flask firmly to the ring stand and add the Buhner funnel with a rubber funnel stopper. 3. Get some filter paper and make sure it fits in the funnel. 4. Place the filter paper in the funnel. 5. Join the side arm flask to source of vacuum. While dealing with this experiment you should always use thick walled tubing, the pressure will collapse with the Tygon tubing. 6. Wet the filter paper with a tiny amount of solvent to be used in the filtration. This technique causes the paper to stick to towards the plate and keeps materials passing under the paper during filtration. Before doing this …show more content…
The solution of liquid and sold is decanted through the filter paper in the funnel. The solid is trapped by the filter and the fluid is drawn through the Buchner funnel into the glass flask by the vacuum. While starting your scientific experiment always remember a vacuum trap and keep it clean so it does not get contaminated. The technique is faster than gravity filtration. Vacuum filtration generally involves the use of vacuum filter flask, water pump, filter trap and sintered glass crucible. It is commonly used in organic chemistry laboratories suction filtration or vacuum filtration. The solution can be supersaturated, unsaturated or saturated. Vacuum filtrations is used to assemble recrystallized

The only pigments visible to the eye are chlorophyll a and chlorophyll b. We know this because chlorophyll reflects the green wavelength of light and shows us that it is present. We also, however, wanted to know what else is present in the spinach leaf.

770 Words | 4 PagesThe sep funnel will be shaken and vented to ensure the products are mixed and pressure is released, and then left while the two solvents settle into two layers. The more dense layer will form at the bottom (the organic layer in this experiment was more dense). The bottom layer was drained and the top layer was extracted again to ensure that all organic products were separated. If the extraction is successful, then the organic compounds are separated and purified, this can be confirmed by TLC and
Separation And Purification Of An Unknown/Complex Compound
379 Words | 2 PagesRecrystallization is a method used for purification and relies on varying solubulites at different temperatures. At low temperatures the solute does not dissolves the chosen solvent, but does in the boiling solvent, and this allows the supersaturation to occur. When the solution is cooled, recrystallization forms for the pure substance, and the impurities remain in the solution. This is caused because the impurities will not fit or bond with the structure of the pure crystallized substance. Then vacuum filtration is used to separate the pure component from its impurities.
Lab Report: Diffusion And Osmosis
1274 Words | 6 PagesIn this lab we used two processes called Diffusion and Osmosis. Diffusion is the movement of molecules from areas of high concentration to areas of low concentration. Diffusion is a process that requires no energy and involves smaller non-polar molecules. In Figure 1 you can see the molecules spreading throughout the glass from the area of high concentration, so that the areas with low concentration are filled evenly as well. The other process was osmosis.
