Answer: The nonpolar solvent are mainly used for the selectively extract fat from a sample vienna sausage.
Explanation: Lipids are all insoluble in polar solvents like water but highly soluble in the non-polar or weakly polar organic solvents, including ether, chloroform, benzene, and acetone. In fact, these four solvents are often referred to as "lipid-solvents" or "fat-solvents"
In the case of extraction one polar and one nonpolar solvent used in such case the fat present in the vienna sausage is well extracted in to nonpolar solvent due to its high solubility. After extraction polar phase seperated out. Fat will obtain after the removal of nonpolar solvent by evaporation.
why was the solvent used able to selectively extract the fat from a sample vienna sausage.
Explain why dichloromethane is a good solvent to remove the fat from the milk? Can you use organic solvent like ethanol to replace dichloromethane in this experiment?
By evaporating the solvent from the extract, she determines that there is only 0.124 g of acid per 10.0 mL of plant extract. What is the ka value for the acid? What is the pH of the plant extract? What is the pH after the following information, calculate the solubility product of AgCN. Calculate the solubility if the pH = 4.75 and the [HCN] is 0.130 M, and the pK_a for HCN is 9.31.
Why were solvents used to extract the pigments from spinach? We used 3 mL of acetone and 3 mL of hexane and then ground the spinach leave in a mortar for 5 minutes.
why is dichloromethane used to extract eugenol in steam distillation?
using the procedures, we used dichloromethane as the unknown
mixture and i was able to extract benzoic acid for an acid,
5-chloro-2-methoxyanaline for a base compound and biphenyl for
neutral compound.
i don't know if that answers the missing part but if it didn't
could you be specific please? thank you!
2. Construct a flow chart of the acid-base extraction you carried out. Use the specific structure of the compounds isolated. Don't use the molecular formula. (15 pts) We used...
Select the reason why deuterated benzene, C6De, is often used as a solvent in NMR spectroscopy. its 2H atoms do not interfere with the sample signal it dissolves a wide array of compounds its H atoms enhance the sample signal it has a low polarity O O O
5. When isolation of a product from a reaction mixture is carried out, a solvent is generally used to extract the product before purification. What boiling point characteristic must this solvent have in order to facilitate its easy separation from the product you want to isolate?
Suppose you were able to choose three fossils to extract DNA from and your goal was to test the hypothesis that completely modern humans evolved in Africa. Which three would you pick? Explain why. Important information: This discussion is to focus on MODERN humans. That means hominids that appeared in the fossil record after 300kya. Please focus on the topic. Consider how you would use DNA to test the origins of modern humans. No discussion of apes, australopithecines and earlier...
During recrystalization, why should a minimum amount of hot solvent be used for dissolving a crude acetanilide solid? Why must the recrystallized solid be washed with cold solvent?
