The best solvent for naphthalene is typically benzene, as it has a similar polarity and can effectively dissolve naphthalene. Other suitable solvents include toluene and xylene, which also provide good solubility due to their aromatic nature. When choosing a solvent, it's important to consider the application and potential health and environmental impacts of the solvents.
What else can I help you with?
What solvent would you use to measure the density of naphthalene acid?
To measure the density of naphthalene acid, a suitable solvent would be a non-polar solvent such as toluene or hexane. These solvents can dissolve naphthalene acid effectively without interfering with its properties. Additionally, using a non-polar solvent helps prevent any potential reactions or solubility issues that might arise with polar solvents. Ensure that the solvent does not alter the measurement accuracy of the density.
How the naphthalene can be purified?
Naphthalene can be purified through a process called recrystallization. This involves dissolving impure naphthalene in a suitable hot solvent, such as ethanol or toluene, and then allowing the solution to cool slowly, which promotes the formation of pure naphthalene crystals. The crystals can then be collected by filtration and washed with cold solvent to remove any remaining impurities. This method effectively separates naphthalene from its contaminants based on differences in solubility.
A sample of 8.76 g of naphthalene is dissolved in 84.5 g of benzene. What is the percent by mass of naphthalene in this solution?
The total mass of solute and solvent is 8.76 + 84.5 = 93.26 g. Percentage of naphthalene = 8.76/93.26 x 100 = 9.39 %.
How naphthalene and potassium sulphate mixture separated from each other?
Naphthalene and potassium sulfate can be separated through a process called recrystallization. Since naphthalene is soluble in organic solvents like ethanol or acetone but potassium sulfate is soluble in water, one can dissolve the mixture in a suitable solvent. Afterward, the solution can be filtered to remove the insoluble potassium sulfate, and naphthalene can be recovered by evaporating the solvent. Alternatively, differences in melting points could also be exploited, as naphthalene has a melting point of about 80°C, while potassium sulfate remains solid at that temperature.
Friedel Crafts acylation of naphthalene depend on type of solvent used?
Yes, the Friedel-Crafts acylation of naphthalene can depend on the type of solvent used. Non-polar solvents like dichloromethane or chlorobenzene are typically preferred as they help maintain the reactivity of the acyl chloride reactant. Polar solvents may interfere with the reaction by complexing with the Lewis acid catalyst or the acyl chloride.
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.
What would be a good solvent at room temperature for naphthalene C10H8 Water ethanol or pentane?
Pentane would be a good solvent at room temperature for naphthalene (C10H8) as it is non-polar and can dissolve non-polar compounds like naphthalene effectively. Water and ethanol are polar solvents and would not dissolve naphthalene well.

Why is naphthalene soluble in ethyl acetate?
Naphthalene is soluble in ethyl acetate due to their similar polarities and the nature of their interactions. Naphthalene is a nonpolar aromatic hydrocarbon, while ethyl acetate is a polar aprotic solvent; however, ethyl acetate has a significant nonpolar character due to its hydrocarbon tail. The dispersion forces and dipole-induced dipole interactions between the nonpolar parts of naphthalene and ethyl acetate facilitate its solubility. As a result, naphthalene can dissolve in ethyl acetate, making it an effective solvent for extracting or dissolving naphthalene.
Why is naphtalene soluble in acetone?
Naphthalene is soluble in acetone because both substances are nonpolar. Acetone is a polar aprotic solvent, which can dissolve nonpolar substances like naphthalene due to the weak van der Waals forces between the acetone molecules and naphthalene particles.
A sample of 8.76 g of naphthalene is dissolved in 84.5 g of benzene. What is the percent by mass of naphthalene in this solution?
The total mass of solute and solvent is 8.76 + 84.5 = 93.26 g. Percentage of naphthalene = 8.76/93.26 x 100 = 9.39 %.

What is the solubility of napathalene in water and ethanol?
Naphthalene is insoluble in water but soluble in ethanol. In water, naphthalene forms a suspension due to its non-polar nature, while in ethanol, it dissolves because of the similar polarities of the solute and solvent.
What is the best solvent to use for removing Gorilla Glue from surfaces?
Acetone is the best solvent for removing Gorilla Glue from surfaces.
What happens to sulphur when it is added to naphthalene?
When sulfur is added to naphthalene, it can form a chemical compound known as sulfurized naphthalene. This can improve the lubricity and anti-wear properties of the naphthalene, making it suitable for use as a lubricant or as an additive in lubricating oils.
