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?
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 %.
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 best solvent for phenol for use in Gas Chromatography?
water
Why is naphthalene more soluble in petroleum ether than in water?
Naphthalene is more soluble in petroleum ether than in water because naphthalene is nonpolar and petroleum ether is also nonpolar. Like dissolves like, so nonpolar solvents like petroleum ether are better able to dissolve nonpolar solutes like naphthalene. Water is a polar solvent and does not interact well with nonpolar solutes like naphthalene, resulting in low solubility.
What is the effect of adding p nitrotoluene to the freezing point of naphthalene?
Adding p-nitrotoluene to naphthalene will lower the freezing point of the mixture. This is due to the phenomenon of freezing point depression, where the presence of a solute lowers the freezing point of the solvent. The greater the concentration of the solute in the solvent, the lower the freezing point will be.
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 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 best solvent to use for removing Gorilla Glue from surfaces?
Acetone is the best solvent for removing Gorilla Glue from surfaces.
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 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.

What is the use of Naphthalene balls at?
they're called mothballs-for moths.
