What else can I help you with?
By which process can you separate a mixture of naphthalene and chalk powder?
Sublimation can be used to separate naphthalene from chalk powder. Naphthalene sublimes at room temperature, while chalk powder does not, allowing for the separation based on this difference in physical properties.
Does the mixture of naphthalene and chalk powder has the smell of naphthalene?
The smell of naphthalene will likely be present in the mixture, although it may be less intense due to the dilution with chalk powder. The naphthalene odor may be detectable, especially in close proximity to the mixture.
What happens when naphthalene and phenolphthalein dissolve in ethanol?
When naphthalene and phenolphthalein dissolve in ethanol it creates a crystal-like powder. The powder will also appear to have a yellow tinge and has no smell.
Can napthaline powder dissolve easily in kerosene?
Yes, naphthalene powder dissolves readily in kerosene, as they are both nonpolar substances. Naphthalene is soluble in nonpolar solvents like kerosene due to similar intermolecular forces.
How will you separate chalk powder iron fillings and naphthalene?
Use a magnet to remove the iron filings... Warm (do not boil) the remaining mixture to evaporate the naphthalene.
Why Naphthalene needs to be ground?
Naphthalene is a white crystalline material that is extensively employed as a moth repellent as well as in the manufacture of other compounds. In some circumstances, before it may be utilized in some applications, naphthalene must be ground or pulverized into a fine powder. Grinding naphthalene improves its surface area, which makes it more reactive and increases its solubility in various solvents. When naphthalene is ground into a powder, more surface area is exposed to the surrounding environment, making it easier to dissolve in solvents or react with other compounds. Additionally, grinding naphthalene can improve its handling qualities. Because naphthalene is brittle and easily breaks into little pieces in its crystalline form, it can be difficult to handle and carry. Grinding it into a powder can improve its stability and make it easier to handle in industrial procedures. To summarize, grinding naphthalene into a fine powder increases its surface area, improves its solvent solubility, and improves its handling qualities. These variables can increase its effectiveness in particular applications and improve the efficiency of naphthalene-based industrial operations.
Is naphthalene soluble to ethyl alcohol?
Naphthalene is said to be somewhat soluble in ethyl alcohol (ethanol). It is insoluble in water and very soluble in ether, chloroform, or carbon disulfide.
What tool can be used to measure the naphthalene in water?
Gas Chromatography is an excellent technique for measuring naphthalene in water.
What is Naphthalene grains?
Naphthalene grains are simply flakes of napthalene, like moth balls or moth flakes, commonly used to deter moths in closets. Naphthalene is a chemical which comes from coal tar, and it is used in a variety of insecticides, lubricants and solvents. The vapour that Naphthalene releases is toxic to insects sucha s moths and silverfish.
Which physical method can be used to separate naphthalene from sand?
Sublimation can be used to separate naphthalene from sand. Naphthalene can be heated to change it directly from a solid to a gas, leaving the sand behind. The gas can then be collected and cooled to form solid naphthalene again.
Is naphthalene a metal or nonmetal?
Naphthalene is a nonmetal. It is an organic compound that consists of carbon and hydrogen atoms.
What is the Bulk Density of Naphthalene flakes?
The estimated bulk density of naphthalene flakes is 36 lb/ft. Naphthalene is most well-known for being the main ingredient used in the production of mothballs.
