sublimation of camphor
Yes, camphor and sodium chloride can be separated by sublimation. Camphor sublimes at a lower temperature than sodium chloride, allowing them to be separated based on the difference in their sublimation points. The camphor will sublime and can be collected separately from the non-sublimed sodium chloride.
Camphor and sodium chloride can be separated by sublimation. When camphor is heated, it sublimes, meaning it changes from a solid directly to a vapor without passing through a liquid phase, and can be collected separately from the remaining sodium chloride.
The experiment will not work because sodium chloride does not sublime. Ammonium chloride appears to sublime upon heating. However, this process is actually decomposition into ammonia and hydrogen chloride gas. NH4Cl + heat → NH3 + HCl (Wikipedia)
Sodium chloride and ammonium chloride can be separated either by sublimation or filtration or crystallization. Sublimation can be found on this site ------------ http://www.lenntech.com/Chemistry/sublimation.htm. I personally think that this method is the easiest.
Sublimation - on gentle heating ammonium chloride will sublime. Sodium Chloride does not and has a high melting point.
The mixture of camphor and sodium chloride can be separated by sublimation. Camphor can be sublimed by heating, leaving sodium chloride behind. The vaporized camphor can then be collected and allowed to solidify back into pure camphor.

Sodium chloride is NaCl, an inorganic salt. Camphor is C10H16O, an organic compound, a terpenoid..

Ammonium chloride can undergo sublimation, meaning it can change from a solid directly to a gas without passing through a liquid state. Sodium chloride does not exhibit sublimation behavior.
Sublimation is a physical change.
To separate ammonium chloride from a mixture of ammonium chloride and sodium chloride, you can dissolve the mixture in water to form a solution. Then, heat the solution to evaporate the water, leaving behind solid ammonium chloride due to its lower melting point compared to sodium chloride. This process is known as crystallization.
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.
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.
