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 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.
How can you make pure crystals of alum from impure alum?
To make pure crystals of alum from impure alum, start by dissolving the impure alum in warm water. Filter the solution to remove any impurities, and then cool the filtered solution slowly. As the solution cools, pure alum crystals will start to form. Carefully collect the crystals and allow them to dry to obtain pure crystals of alum.
