What is the practical advantage of having the organic solvent more dense than water when one is extracting an organic compound from an aqueous solution in a separatory funnel?

differences in the density of solvents allow the separation of two phases..Organic solvents like CH2Cl2, CHCl3 having higher density than water remains at the lower part of separatory funnel which can be easily collected via the stopcock at the end of funnel.
*extracting solvent shouldn't be miscible with water, otherwise there will be no separation despite of differences in their densities

How can you extract a solute?
A solvent extraction is best done by using a separatory funnel. Add your compound to one of the two immiscible solvents and add everything to the funnel. Invert it once or twice, making sure to release any accumulated gas to prevent a buildup of pressure. The compound will naturally pick the solvent that it is more soluble in. Then drain them out one at a time. You're compound will be present in one of them.
What is the advantage of having the organic solvent be denser then water when extracting an organic compound?
The difference in density allows you to separate out the components. DCM is much more dense than water, so any compounds that are dissolved in DCM will stay below the aqueous layer. This is extremely useful in acid/base reactions.
What practical application might be made of the tollen's reaction?
The most practical application of the Tollen's reaction is to detect an aldehydic group in a compound. The reaction is as follows: RCHO + 3OH- + 2[Ag(NH3)2]+ --> RCOO- + 2H2O + 2Ag + 4NH3.
What is metal ores?
Metallic ores are rocks that contain metals.Sometimes it contains a metal compound, like Hematite, an ore of Iron, Fe2O3, for example. They can also contain metals that are found in their pure form, like copper (which can form compounds, but not usually when found in ore) and Gold (which does not form compounds). This is known as a 'native' metal.
Is artificial sweeteners a compound or mixture?
mixture
Is practice a compound word?
No, practical is not a compound word. It is not a word that is made up by the combination of two other words.

What is An advantage of a compound light microscope over a single lens microscope?
A compound light microscope is able to provide more clarity and detail than a single lens microscope, which is its advantage. Compound refers to the microscope having more than one lens.
What is the major advantage of a compound DC generator?
The compound DC motor has the advantage of both, constant speed feature of the shunt motor and the capability to handle high starting torque feature of series motor.
Who estimated the value of pi and invented the compound pulley?
Archimedes accurately estimated the value of pi. He was also the Greek inventor that created the compound pulley and first device used for extracting water from below the surface of the earth as well.
Which is easiest to separate solution compound mixture or element?
The answer is very specific for each practical case !
What reaction takes place when extracting elements from a compound?
A decomposition reaction breaks down a compound into its elements. For example, when an electric current is passed through water, it decomposes into hydrogen gas and oxygen gas. 2H2O --electrolysis--> 2H2 + O2
