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.
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.
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.
What is iodo-naphthalene used for?
Iodo-naphthalene is used as a reagent in organic synthesis to introduce iodine atoms into molecules. It can also be used as a precursor in the preparation of other chemicals and as a source of iodine in various reactions.
Is naphthalene soluble to ethyl alcohol?
Yes, naphthalene is sparingly soluble in ethyl alcohol. It has low solubility in most organic solvents, including ethyl alcohol.
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 is a white crystalline compound used in mothballs to repel insects. Naphthalene grains refer to the solid form of naphthalene that can slowly evaporate to release its insect-repelling scent. They are often used in closets, drawers, and storage containers to protect clothing and fabrics from pests.
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.
What is calorific value of naphthalene?
100mjkg1
