What else can I help you with?
How do you account for the observed solubility of naphthalene and sodium chloride in water and ether based on the nature of the bonds that exist in them?
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.
Do naphthalene dissolves in water?
Naphthalene is not very soluble in water, meaning it does not dissolve easily in water. The solubility of naphthalene in water is very low.
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.
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 does paradichlorobenzene dissolve in naphthalene?
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.
How can we separate naphthalene from sand?
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.
What organic solvents can dissolve naphthalene?
Organic solvents that can dissolve naphthalene include benzene, toluene, xylene, and tetrahydrofuran (THF). These solvents have a non-polar nature and are capable of breaking the intermolecular forces holding naphthalene together.
Do naphthalene crystals dissolve in mineral oil?
Yes, naphthalene crystals are soluble in mineral oil, as both are nonpolar substances. When naphthalene is added to mineral oil, it dissolves to form a homogeneous solution.
Is naphthalene in alcohol?
Naphthalene is not soluble in alcohol; it is more soluble in organic solvents like benzene or chloroform. However, small amounts of naphthalene can dissolve in alcohols like ethanol due to its nonpolar characteristics. In general, naphthalene's solubility in alcohols is limited and varies with concentration and temperature.
What happens when naphthalene is added to 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.
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.
Is naphthalene soluble in cyclohexane?
Naphthalene is a neutral organic compound, but is insoluble in HCl. It is an aromatic hydrocarbon that is primarily used in mothballs.
