Why camphor sublimes on heating but common salt does not?

Why camphor sublimes on heating but common salt does not?

Common salt is not sublime and on heating it will turn into molten form or will get fused. Whereas camphor is sublime in nature and gets easily converted into vapours which on cooling gets solidified in its pure form. Commonsalt does not possess such properties.

Can you use sublimation to separate salt and sand?

Answer: Sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase. Explanation: sand and salt can not be separated through the method of sublimation because none of the two can show sublimation(even when heated).

What substances can be purified by sublimation?

Benzoic acid, comphor and naphthalene sublime on heating hence, they are purified by sublimation method.

Is nacl a sublimated substance?

Sodium chloride is an ionic solid and has high melting and boiling points. Therefore, it cannot change in the vapor phase simply at atmospheric pressure so it cannot sublimate.

Can we separate a mixture of camphor and naphthalene by sublimation?

Naphthalene and camphor cannot be separated by sublimation.

Can you separate a mixture of camphor and ammonium chloride by sublimation Why?

Mixture of ammonium chloride and salt can be separated by sublimation. As camphor is not a salt the mixture of camphor and ammonium chloride was not separated by sublimation.

Is common salt sublimated?

Common salt is not a sublimating substance and so it cannot be separated from its solution by sublimation.

Can urea be purified by sublimation?

Sublimation cannot be used for purification of urea.

Which of the following Cannot be purified by sublimation?

Oxalic acid does not undergo sublimation , hence it does not get converted into pure vapours which give back the pure substance after cooling. All the other substances Iodine, naphthalene and camphor undergo sublimation.

Which of the substance is not purified by sublimation?

Explanation: Sublimation cannot be used for purification of urea. Explanation: Sublimation is the one of the purifying method for the purify the organic materials.

Can salt sublimate?

Answer: The changing of a solid directly into vapours on heating, and of vapours into solid on cooling is called Sublimation. Iodine sublimes on heating whereas common salt does not sublime on heating. So, we can separate iodine from a mixture of Common salt and Iodine by the process of sublimation.

Which of the following Cannot be separated by sublimation?

Class 9 Question Iodine and ammonium chloride Nh4cl cannot be separated by sublimation because for sublimation process to take place one component should be sublime that is ammonium chloride and the another component would be non- sublime. Thus, these components cannot be separated by sublimation.

Why is sublimation not used to separate a mixture of salt and sand?

If, by “salt”, you mean sodium chloride, then it does not sublime, not does sand. If they did, then the temperature would be so high that normal laboratory equipment would melt if it was made of glass. If you mean another type of salt, some decompose into smaller compounds, some dissociate and most melt at very high temperatures.

Can you use sublimation to separate ammonium chloride?

Indeed, sublimation can be used to separate salt and compounds such as ammonium chloride which do sublime. Salt does not sublime. You will need to add water to dissolve the salt (Sodium chloride). Send the solution through a filter paper.

Which is an example of a sublimable substance?

Examples of sublimable substances- ammonium chloride, camphor, iodine, naphthalene, anthracene etc. Keeping this in consideration, which of the following mixtures Cannot be separated by sublimation? A . Salt and ammonium chloride. B . Salt and naphthalene. C . Salt and camphor. D . Camphor and naphthalene. Also, how do you separate camphor?
