What is the purpose of the sublimation and recrystallization steps?

Recrystallization and Sublimation are two commonly encountered methods of Purification. Several of these are done in the laboratory to obtain a pure sample of a particular organic compound.
Recrystallization literally means to crystallize again.
Sublimation involves heating the compound at low pressure from one apparatus and and condensing it in another. This is quite the same as distillation but of solid state.

How do you purify solid organic compound?
Many methods exist: precipitation and filtration, distillation, dissolution and recrystallization, sublimation, sedimentation etc.
What steps can be taken to purify and isolate salt found in mines?
The principal steps are: grinding, dissolution in water, filtering, refining by repeated crystallization/recrystallization processes.
What are the nine steps of the water cycle?
Evaporation, condensation, advection, percipitation, runoff, groundwater, infiltration, transpiration, and sublimation(not in order)
For what purpose is charcoal used in recrystallization?
Activated carbon is also known as decolorizing carbon. It is used to remove the colored impurities from the sample. Activated carbon provides a high surface area to absorb colored impurities. http://designer-drugs.com/pte/12.162.180.114/dcd/chemistry/equipment/recrystallization.html
What do you call the process of a solid changing to a gas?
sublimation. for example when dry ice changes directly to a gas.

What is the purpose of recrystallizing a solid?
Purification, and/or the production of larger/typical crystals.
Is KCL and NaCl is separated by sublimation?
Sodium chloride is not purified by sublimation.
What is a sentence for recrystallization?
the magma or lava heats the rock it is in contact with, causing recrystallization

What purpose did the vacuum serve during the sublimation purification of caffeine?
it is used because some organic compounds do not sublime at atmospheric pressure so by using the vacuum it substantially reduces the pressure so that they can be purified by sublimation. it also makes decomposition and melting less likely to occur during the sublimation.
Why is sodium chloride not suitable for recrystallization?
The crystallization/recrystallization of sodium chloride from water solutions is frequently used.

What is the importante of recrystallization?
For purification
What is the process called when ice turns into water vapor?
I think the answer is sublimation
