What substance can be purified by sublimation?

Sodium chloride is not purified by sublimation.

When the organic compound is volatile in nature and the impurities aren't volatile in nature, Sublimation is used for example Camphor is purified through sublimation

Several organic compounds can be purified by sublimation in vacuum.

Table salt is purified by filtration and repeated crystallization/recrystallization.

The sublimation temperature of every substance is different.

Yes, purified water is classified as a pure substance. It is a pure substance because it does not have any contaminants.

Because salt doesn't sublime !

The reason for sublimation is so the substance transition from a gas directly to a solid without becoming a liquid at all.

The substance is purified/cleansed or refined.

Sublimation is a technique used by chemists to purify compounds. Typically a solid is placed in a sublimation apparatus and heated under vacuum. Under this reduced pressure the solid volatilizes and condenses as a purified compound on a cooled surface (cold finger), leaving a non-volatile residue of impurities behind. Once heating ceases and the vacuum is removed, the purified compound may be collected from the cooling surface.

by the process of sublimation

You may have your terms backward. Sublimation is the disappearance of the solid phase material in favor of the vapor phase material. No solid substance is formed during sublimation.

In the process of sublimation, a substance goes from the solid state directly to the gas state.

It depends on the substance.

Well iodine,napthelene and camphour are some substance that show sublimation

That is called sublimation.

A sublimation or melting

vapour pressure of common salt is higher... hence it cannot be sublimed...

Sublimation is when a substance goes from a solid to gas state, without an intermediate liquid phase.

Sublimation is when a substance turns from a solid to a gas (or the reverse). This can occur when blowing on dry ice or in volcanoes.

The sublimation of dry ice is the chemical released predeceasing the addition of the oxogen substance Mc45.

They are related,because sublimation is a transition of a substance directly from the solid phase to the gas phase.

Sublimation occurs when the particles of the substance must move from being very tightly packed to being spread far far apart. Thus, sublimation is an endothermic change because energy is gained by the substance as it changes state

Sublimation is the changing of a substance directly from a solid to a gas without turning to a liquid. Sublimation occurs at temperatures and pressures below the solids triple point.

Sublimation occurs when the particles of the substance must move from being very tightly packed to being spread far far apart. Thus, sublimation is an endothermic change because energy is gained by the substance as it changes state.
