To avoid supercooling. Supercooling may occur if a liquid is cooled too quickly. It's temperature falls below it's normal freezing point without the appearance of solid.

During the cooling of the naphthalene why the boiling tube must be placed in a conical flask?

Placing the boiling tube in a conical flask during the cooling process helps to prevent any naphthalene vapor from escaping into the environment. The conical flask acts as a containment vessel, allowing the naphthalene to condense back into solid form inside the boiling tube, making it easier to collect and handle afterward. Additionally, this setup minimizes any potential hazards associated with inhaling the vapors.


How do naphthalene balls become smaller. name the process?

Naphthalene balls decrease in size due to sublimation, a process where the solid naphthalene directly transitions into a gas without passing through the liquid phase. This gradual transition causes the naphthalene balls to shrink over time.


During the cooling of naphthalene explain why the naphthalene must be stirred continuosly?

Stirring the naphthalene continuously during cooling helps to promote even heat distribution and prevent the formation of hot spots. This ensures that the naphthalene cools uniformly, reducing the risk of crystallization issues and improving the overall quality of the solid product.


How do you separate naphthalene from sand?

One way to separate naphthalene from sand is by sublimation. By heating the mixture, the naphthalene will undergo sublimation, turning into a gas and leaving behind the sand. The gas can then be collected and cooled back into solid naphthalene.


What is the solute and solvent of naphthalene on air?

In this context, the solute is naphthalene while the solvent is air. Naphthalene is the substance that is being dissolved in the air.

Why is the naphthalene solution cooled in an ice bath before vacuum filtration by recrystallization?

Cooling the naphthalene solution in an ice bath helps to promote the formation of pure crystals by reducing the solubility of impurities. When the solution is cooled, the naphthalene crystallizes out, while most impurities remain dissolved in the solution. This improves the efficiency of the vacuum filtration process by ensuring a higher purity product.

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.


Why a gray color in naphthalene sample after usual purification process?

The gray color in a naphthalene sample after the usual purification process could be due to impurities that were not completely removed during the purification process. It is possible that the impurities present in the sample contributed to the gray coloration. Additional purification steps may be necessary to obtain a pure white sample of naphthalene.


What is the process of separating water and naphthalene?

Filtration because it says that it can separate fine solid from liquids.


How do you make liquid naphthalene?

Liquid naphthalene is typically obtained by melting solid naphthalene. This can be done by heating solid naphthalene to around 80 degrees Celsius until it liquefies. It is important to handle naphthalene with care as it is toxic and flammable.

In this context, the solute is naphthalene while the solvent is air. Naphthalene is the substance that is being dissolved in the air.


How can naphthalene be separated from a mixture of naphthalene and common salt.explain?

Naphthalene can be separated from common salt by sublimation since naphthalene sublimes at a lower temperature than common salt. By heating the mixture, naphthalene will turn directly from a solid to a gas, leaving behind the common salt as a solid residue. The naphthalene gas can then be cooled and collected back as a solid.


Is the naphthalene soluble in Chloroform?

Yes, naphthalene is soluble in chloroform. When added to chloroform, naphthalene dissolves because they have similar solubility characteristics.
