naphthalene and iodine can be separated by sublimation
Wiki User
∙ 11y ago
Yes, iodine and naphthalene can be separated by sublimation because they have different sublimation points. Iodine sublimes at a lower temperature compared to naphthalene, allowing for the selective separation of the two substances based on their sublimation properties.

How will you separate naphthalene from mixture of naphthalene and sodium chloride?
Naphthalene can be separated from sodium chloride by sublimation. When the mixture is heated, naphthalene will sublimate, turning from a solid to a gas, and can be collected separately from the solid sodium chloride.
How can naphthalene be separated from a mixture of naphthalene and common salt.explain?
Naphthalene can be separated from common salt by sublimation since naphthalene sublimes at a lower temperature than common salt. By heating the mixture, naphthalene will turn directly from a solid to a gas, leaving behind the common salt as a solid residue. The naphthalene gas can then be cooled and collected back as a solid.
How do you separate naphthalene from sand?
One way to separate naphthalene from sand is by sublimation. By heating the mixture, the naphthalene will undergo sublimation, turning into a gas and leaving behind the sand. The gas can then be collected and cooled back into solid naphthalene.
How can crystal of iodine and charcoal could be separated?
Iodine crystals and charcoal can be separated by sublimation. When iodine is heated, it sublimes directly from solid to gas without passing through the liquid phase, leaving behind the charcoal. The iodine vapor can then be collected and cooled to form solid iodine crystals again.
What is sublimation and examples of substances that can sublime?
Sublimation is the process where a substance transitions from a solid directly to a gas phase without passing through the liquid phase. Examples of substances that can sublime include dry ice (solid carbon dioxide), camphor, and mothballs (naphthalene).
Can you give me 5 examples of sublimation?
Dry ice sublimating from solid to gas without melting into a liquid. Mothballs gradually evaporating in a closet without leaving behind a liquid residue. Snow disappearing into vapor without melting into water. Freeze-dried food removing moisture through sublimation to preserve flavor and texture. Iodine crystals turning directly into purple vapor without melting first.
What do you meant by sublimation also give example?
Sublimation is the process of direct transformation of a solid in a gas: examples are iodine, naphthalene, dry ice, camphor.
How do you separate naphthalene from sand?
One way to separate naphthalene from sand is by sublimation. By heating the mixture, the naphthalene will undergo sublimation, turning into a gas and leaving behind the sand. The gas can then be collected and cooled back into solid naphthalene.
What is sublimation and examples of substances that can sublime?
Sublimation is the process where a substance transitions from a solid directly to a gas phase without passing through the liquid phase. Examples of substances that can sublime include dry ice (solid carbon dioxide), camphor, and mothballs (naphthalene).
By which process can you separate a mixture of naphthalene and chalk powder?
Sublimation can be used to separate naphthalene from chalk powder. Naphthalene sublimes at room temperature, while chalk powder does not, allowing for the separation based on this difference in physical properties.
The chemical equation of iodine solid to gas?
The chemical equation for the sublimation of iodine solid to iodine gas is: I2(s) -> I2(g). This represents the process in which solid iodine directly transforms into iodine gas without going through a liquid phase.
Can you separate mixtures of ammonium chloride and naphthalene by sublimation?
yes but only by fractional sublimation (sublimating point of these substances are different)
Why naphthalene undergoes sublimation but has melting point?
Similar to dry ice (solid CO2), pressure is necessary for the formation of liquid naphthalene.
Explain what is meant by the sublimation of iodine at 184 C?
We know that iodine's heat of sublimation is 56.94cal/g, so I believe that you can find the heat of sublimation at a specific temperature if you have a know amount of grams.
How do naphthalene balls become smaller. name the process?
Naphthalene balls decrease in size due to sublimation, a process where the solid naphthalene directly transitions into a gas without passing through the liquid phase. This gradual transition causes the naphthalene balls to shrink over time.
What do you call when iodine crystals turn to iodine haze?
When iodine crystals turn to iodine haze, this process is called sublimation. Sublimation refers to when a solid substance transitions directly into a gas without passing through the liquid state.
Which halogen is purified by sublimation?
Iodine is the halogen that is commonly purified by sublimation. When iodine is heated, it directly changes from a solid to a gas without passing through the liquid phase, allowing impurities to be left behind in the solid form.
