What will melt faster pure or impure naphthalene?
Impure naphthalene will typically melt faster than pure naphthalene. The impurities present in impure naphthalene lower its melting point, making it easier for the solid to convert into a liquid state at a lower temperature.
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.
How can we purified naphthalene by sublimation?
Naphthalene can be purified by sublimation due to its ability to transition directly from solid to gas without passing through a liquid phase. To perform the sublimation, heat the impure naphthalene in a controlled manner, allowing it to vaporize. The vapor then condenses on a cooler surface, typically a cold glass or metal surface, forming pure naphthalene crystals. This method effectively separates naphthalene from non-volatile impurities that do not sublimate.
Is pencil point pure or impure?
Pure
Why is naphthalene a pure substance?
Naphthalene is considered a pure substance because it is a chemical compound made up of only naphthalene molecules. It has a definite and consistent chemical composition, with uniform properties throughout its structure.

what the between pure and impure water?
Pure water does not contain colour but impure water contains Other compounds.
What advantage does an impure mixture have over pure substance?
Generally an impure material is cheaper than a pure material; the word advantage is not so adequate here - can use pure or impure, this depends on the specific applications.
