Substances that don't sublime.
Solutions cannot be separated by sublimation.
The mixture of iodine and camphor cannot be separated by sublimation because both substances have different sublimation points. Iodine sublimates at a lower temperature than camphor, which means that when heated, iodine will vaporize while camphor remains solid. As a result, the process would not effectively separate the two components; instead, it would lead to the loss of iodine in the vapor phase without isolating camphor. Therefore, other separation methods, such as solvent extraction or recrystallization, are more suitable for this mixture.
Sublimation refers to a substance changing from a solid directly into a gas, and can usually only be achieved via decrease in air pressure as well as temperature. Fractional sublimation refers to separating a substance's parts through the sublimation of one part.
A substance that cannot be separated physically is a pure substance.
An element cannot be separated into simpler substances by chemical means.
Solutions cannot be separated by sublimation.
Yes, iodine and naphthalene can be separated by sublimation because they have different sublimation points. Iodine sublimes at a lower temperature compared to naphthalene, allowing for the selective separation of the two substances based on their sublimation properties.
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.

Iodine sublimes at a lower temperature than camphor, so when the mixture is heated, both substances will sublimate. This will make it difficult to separate the two as they will sublime at different rates and mix together.
Because salt doesn't sublime !
A substance that cannot be separated physically is a pure substance.
An element cannot be separated into simpler substances by chemical means.
Yes, a mixture of iron and sulfur can be separated by using a magnet to attract the iron filings and then using a process called sublimation to separate the sulfur from any remaining particles.
Common salt, or sodium chloride, cannot be purified by sublimation because it has a high melting point (801°C) and does not sublime at normal temperatures and pressures. Sublimation is the process of a substance transitioning directly from a solid to a gas without passing through the liquid phase, which is not applicable to sodium chloride.
The mixture cannot be separated after it is baked.
