Study Notes
Crystallization
- Crystallization is the process by which solid forms, where the atoms or molecules are highly organized into a structure known as a crystal.
Recrystallization
- Recrystallization is a laboratory technique used to purify solids based on their different solubilities.
- The purpose of vacuum filtration in recrystallization is to separate the crystals from the mother liquor.
- The steps in the recrystallization of compounds are: dissolving the impure solid in a solvent, filtering the solution, and allowing the solution to cool and crystallize.
- During recrystallization, impurities are left behind in the mother liquor, resulting in a pure crystal.
Crystal Formation
- Crystals can form through various ways, including: slow cooling of a saturated solution, slow evaporation of a solvent, or rapid cooling of a solution.
Recrystallization Process
- In the recrystallization process, the impure solid is dissolved in a solvent to form a solution, and then the solution is allowed to cool and crystallize, resulting in a pure crystal.
- The attributes of the resulting crystal are largely determined by factors such as: the temperature, pressure, and concentration of the solution.
Process Description
- Recrystallization is a process of purifying a solid by dissolving it in a solvent, filtering, and then crystallizing the resulting solution.
