Why Camphor can easily be purified by the process of sumlimation and common salt cannot be purified by sublimation?
Camphor is a molecular compound, with a molecular formula C10H16O. Because it is molecular and the solid is "held together" by inter-molecular forces it has a lower melting point 175 C and boling point 204C than sodium chloride mp 800+C. bp 1400+ C. Under gentle heating solid camphor has a a reasonable vapor pressure and sublimes (no melting or boiling required -as it is flammable care is needed.) Sodium chloride a giant ionic lattice held together by strong electrostatic bonds when under heated gently has virtually no vapor pressure and does not sublime.
What water salt or purified helps plants grow?
purified
What are the differences between the appearance of rock salt and purified salt?
Rock salt (impure salt) is frequently colored.
Describe how you will attempt to recover pure common salt from a mixture of sand common salt and ammonium chloride?
To recover pure common salt from a mixture of sand, common salt, and ammonium chloride, I would first dissolve the mixture in water, allowing the common salt and ammonium chloride to dissolve while the sand remains insoluble. Next, I would filter the solution to separate the sand from the salt solution. Then, I would gently heat the salt solution to evaporate the water, leaving behind pure common salt as a solid residue. The remaining ammonium chloride can be removed by sublimation if needed, but this step is optional depending on the desired purity.
What is similar about distilled water and salt water?
The 2 parts hydrogen and 1 part oxygen. Distilled water is water "purified" by distillation. Salt water is water with salt in it.
Why common salt cannot be purified by sublimation?
Because salt doesn't sublime !
How is impure common salt purified?
Impure common salt can be purified through the process of recrystallization. This involves dissolving the impure salt in water, filtering out any insoluble impurities, and then allowing the solution to cool slowly so that pure salt crystals form. These crystals can then be separated and dried to obtain purified common salt.

Is KCL and NaCl is separated by sublimation?
Sodium chloride is not purified by sublimation.
What water salt or purified helps water?
purified
What method is used to separate ammonium chloride and common salt?
Ammonium chloride and common salt can be separated by sublimation, as ammonium chloride sublimes at a lower temperature compared to common salt. When heated, the ammonium chloride will turn into a gas and can be collected separately from the remaining common salt.
What water salt or purified helps plants grow?
purified
Does common salt sublime?
No, common salt does not sublime. Sublimation refers to the process by which a solid directly transforms into a gas without passing through the liquid phase. Salt will instead melt when heated, before eventually vaporizing.
What is purified salt?
Salt that has had any contaminates removed.
Does purified or tap water hold more salt?
It all depends on what you mean. Tap water has more salt than purified water but purified water can hold more salt if salt is added. There is more room, so to speak, for the salt ions to fit into a container.
Why should you use sublimation to separate the mixture of salt and ammonium chloride?
Because ammonium chloride can be removed from salt by sublimation (at a given temperature).
How can you separate ammonium chloride from salt?
By sublimation
