When is purification by sublimation applicable?
Purification by sublimation is applicable when the compound of interest has a much lower or higher vapor pressure compared to the impurities, allowing for selective purification by converting the compound directly from solid to vapor state and back to solid without passing through the liquid phase. This method is effective for separating volatile compounds from non-volatile impurities or vice versa, and is commonly used in industries such as pharmaceuticals and semiconductors for purifying substances.
Where sublimation is used?
Sublimation is used in the process of converting a solid directly into a gas without passing through the liquid phase. It is commonly used in the production of freeze-dried foods, in the purification of substances such as iodine, and in the creation of air fresheners and deodorizers.
What is the importance of sublimation?
Sublimation can be important during the recovery of compounds that are suspended or dissolved in a fluid or a solid such as dry ice. Sublimation is the transition of a substance from a solid to a gas without passing through the liquid phase.
How does sublimation work in science?
Sublimation is the process of a solid to gas without being turned into a liquid. One must find a phase diagram of the substance. The triple point where all three phases can mannerly exist. So when one finds point below this, and a pressure and temperature where liquid doesn't exist the solid will become gas.

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.
Why is crystallization a much better purification technique than simply washing the crystals with cold solvent?
because sublimation is a method of obtaining a product of high purity; it is best adapted to use with small amounts of material; there is little loss of material in sublimation; and the process of sublimation requires less time and transferring.

What are the applications of sublimation in chemistry?
Sublimation is the primary process by which dry ice turns into carbon dioxide. This process uses energy from the atmosphere which causes a cooling effect. Many people use dry ice to keep things cold, such as during hunting or fishing trips.
