What is degree of supersaturation?
The ratio of observed solubility to that of equilibrium solubility is the degree of supersaturation
Is the ability to be dissolved density?
no, it is solubility
Which solubility of salt increase with the increase in temperature?
The movement of the particles in the solute and between solute and solvent are amplified at higher temperature and the solubility increase.
How the solubility of gases in liquids is affected by temperature changes?
When it is on movement it has more energy ---------------------- The solubilty of gases in liquids is increased when the temperature is lowered and the pressure is increased.
Can solubility be increased by stirring?
Solubility can be increased in solvent and by adding more solute.
What is the chemical formula of Fluorene?
C13H10
What does fluorene coonduct?
What does fluorine conduct
What has the author Marlyn Homer Bortner written?
Marlyn Homer Bortner has written: 'The crystal structure and molecular structure of fluorene' -- subject(s): Fluorene
Which is more polar fluorene or florenone?
The fluorenone is more polar because it belongs to the ketone family. The fluorene is an aromatic molecule without polar fonction and this is not the case of the fluorenone, it contains a carbonyl fonction (carbon-double bond-oxygen).
Mechanism of oxidation of fluorene to fluorenone?
I'm not positive about the correct mechanism, but I can propose one that seems plausible. Oxygen can exist as a singlet or triplet species. The triplet species (O-O with 2 lone pairs and a radical on each O) is the ground state species, so unless O2 is excited, it will most likely react in this manner. Using that assumption, O2 can abstract a proton radical from flourene to form a fluorene radical (with the radical at the benzylic position). This is the initiation of a radical chain process. Next, the peroxy radical can attach to the fluorene radical (thus terminating the chain). Alternatively, another O2 molecule can attach to the fluorene radical. This peroxy fluroene radical can abstract a proton from a fluorene molecule, propogating a fluorene radical. In either case, the resulting species is a peroxy fluorene molecule. Now, you can draw a mechanism where a hydroxide anion (the reaction is run in base) pulls off the remaining benzylic proton, pushing electrons into a carbon to oxygen pi bond, and breaking the oxygen-oxygen single bond to release hydroxide. As I said, I have no evidence for this mechanism, just using my chemical knowledge and experience.
How do you separate o-toluic acid from a mixture of o-toluic acid and fluorene and 1 4-dibromozene?
To separate fluorene from toluic acid, one can oxidize the fluorene to fluorene in air by dissolving the mixture in a mix of toluene and strong sodium hydroxide. By adding a phase transfer catalyst like Aliquat, the two components can be separated.
Why does fluorene move faster down the column chromatography than fluorenone?
Well it depends on the solvent you are using, but lets assume you use pentane as the solvent for fluorene and diethyl ether as the solvent for fluorenone. Used in this order, fluorene should actaully move slower down the column due to the the polarity of the alumina and the nonpolarity of the solvent (pentane). Since fluorene is less polar so, remember the rule like dissolves like? Well, this kind of applies to chromatography wherein rather than dissolve just replace it with moves with, so like moves with like. That being said the pentane will "carry" the fluorene through the alumina slower than the latter (which I will explain). Fluorenone is polar because of its C=O bond, that being said the dielectric constant of diethyl ether is 4.3 which means it has intermediate polarity (remember that pentane has a dielectric constant of 2.1 I think, so it is nonpolar). Since the alumina, diethyl ether, and the fluorenone are all polar, the fluorenone will travel faster through the alumina than would the fluorene, because there is no attraction between all these polar compounds which will allow it to move faster, rather than a nonpolar and polar chemical having an attration towards each other and thus moving more slowly. Hope this helps, Branden
What is difference between apparent and intrinsic solubility?
Apparent solubility represents the solubility one observed during the experiment while the intrinsic solubility meant to the real or true solubility.
What is the quality of a substance that allows it to dissolve?
if an object is aqueous it can dissolve
What is the ability of one material to dissolve in another?
The ability of one substance to dissolve in another substance is called SOLUBILITY.
The ability of a substance to dissolve in a solvent is called?
The ability of a solute to dissolve in a solvent at a certain temperature is called solubility. The solubility of most solids in water increases with temperature increases.
What part of speech is solubility?
Solubility is a noun.
