What is the process of sublimation of camphor?

What is the process of sublimation of camphor?

Camphor converts directly into its gaseous state without converting into liquid state. This property of camphor helps to separate it from NaCl. The process is called sublimation. So when a mixture of sodium chloride and camphor is heated, camphor gets sublime and gets directly converted into vapor form.

Can camphor and sodium chloride be separated by sublimation?

Camphor is a sublimable volatile solid, whereas sodium chloride is a non-sublimable solid. Therefore, the mixture of camphor and sodium chloride can be separated by the process of sublimation.

Which method is suitable for separation of camphor and sodium chloride Why?

Sublimation is the process which is used to separate the mixture of camphor and salt. Camphor gets directly converted to its gaseous state, leaving the salt behind.

Can sodium chloride be sublimated?

Answer: B) sodium chloride Sublimation is the process of a substance changing directly from the solid to the gas phase without passing through the intermediate liquid phase. Iodine and ammonium chloride produces fumes on gentle heating while sodium chloride does not sublime.

What type of change is sublimation of camphor?

Sublimation of camphor is a physical change.

Why camphor is separated by sublimation?

As we know sublimation is the process in which solid directly converted into gas. As the camphor and iodine are sublime compound. So upon heating or sublimation both goes to gaseous state.

Is Nh4cl sublimable?

Ammonium chloride, a sublimable solid undergoes thermal dissociation on heating. It is an example of sublimation. This change consists of both physical and chemical changes.

Does camphor undergo sublimation?

If camphor is left out in the air, it sublimates while paraffin wax does not. So, camphor is considered a sublimating substance.

Does camphor sublime?

Camphor sublimes slowly as room temperature; once vaporized it can react with and soften many plastics.

Is sublimation of camphor a physical or chemical change?

In case of sublimation of camphor, the solid (camphor) is converted into vapor and no new substance is formed. Hence it is the physical change.
