WebJun 21, 2024 · The process of crystallization takes place in three stages: nucleation, crystal growth, and laboratory uses of crystallization. Nucleation: The first stage or step in the process of crystallization is nucleation. Among the atoms, the first to form a crystal becomes the center of the nucleation and more atoms are formed around that nucleus.
WebApr 7, 2024 · Figure 3.1: Various crystals. Crystallization is used in the chemistry laboratory as a purification technique for solids. An impure solid is completely dissolved in a minimal amount of hot, boiling solvent, and the hot solution is allowed to slowly cool. The developing crystals ideally form with high purity, while impurities remain in the ...
