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.
One way is to dissolve the ammonium chloride in water, then recover the ammonium chloride by evaporation; the naphthalene will not dissolve in water in any substantial quantity.
To stop it from blowing up.
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.
Naphthalene is a white crystalline solid with a distinctive mothball odor. It has a melting point of 80.2Β°C and a boiling point of 218Β°C. It is insoluble in water but soluble in organic solvents.
Naphthalene is not very soluble in water, meaning it does not dissolve easily in water. The solubility of naphthalene in water is very low.
Gas Chromatography is an excellent technique for measuring naphthalene in water.
Naphthalene is sparingly soluble in water, so when added to water it will partially dissolve but will mostly float on the surface. Naphthalene is volatile, so it will slowly vaporize into the air.
Yes, naphthalene is sparingly soluble in ethyl alcohol. It has low solubility in most organic solvents, including ethyl alcohol.
Paradichlorobenzene dissolves in naphthalene because they are both nonpolar compounds. Nonpolar substances are soluble in nonpolar solvents like naphthalene due to similar attractive forces between molecules, known as London dispersion forces. This allows paradichlorobenzene to mix and dissolve evenly in naphthalene.
Naphthalene is strictly non-polar with a structure similar to two benzene rings linked together. Similarly ether is also highly non-polar. Since like dissolves like naphthalene is soluble in ether.
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.
The reason why naphthalene can be dissolve in ether and not in water is because of their polarity. Naphthalene is a non-polar molecule. so it can only dissolve with a non-polar molecule.
Sodium carbonate is more soluble in water than calcium carbonate and naphthalene. Sodium carbonate is a water-soluble salt, while calcium carbonate is sparingly soluble in water, and naphthalene is insoluble in water.
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.
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.
To separate a mixture of naphthalene and ammonium chloride, you can use sublimation. This involves heating the mixture, causing the naphthalene to sublime (change from a solid to a gas) and leaving the ammonium chloride behind. The naphthalene gas can then be collected and cooled to form solid naphthalene again.
