RECRYSTALLISATION Meaning and
Definition
-
Recrystallization is a process in which a solid substance, often a crystalline material, forms new, pure crystals from a saturated solution or melt. It is a purification technique commonly used in chemistry and materials science to obtain a pure compound from an impure mixture.
The process of recrystallization typically involves dissolving the impure substance in a suitable solvent at an elevated temperature. The solute dissolves to form a saturated solution, which is then allowed to cool slowly. As the solution cools, the solute molecules or ions come together, rearrange, and form new crystal structures. The pure crystals are then separated from the remaining solvent and impurities using techniques such as filtration or centrifugation.
Recrystallization is an effective method for removing impurities, as the impurities are often less soluble in the solvent compared to the desired compound. The process exploits differences in solubility to separate the compound of interest from the impurities.
The quality and purity of the resulting crystals greatly depend on various factors, including the choice of solvent, the rate of cooling, and the removal of impurities during the process. Recrystallization is widely used in the pharmaceutical, chemical, and materials industries to obtain pure compounds suitable for further analysis and applications.
In summary, recrystallization is a purification technique that involves dissolving an impure substance, allowing it to crystallize from solution, and isolating the resulting pure crystals. It is a crucial method for obtaining high-quality compounds in various fields of science and industry.

Etymology of RECRYSTALLISATION
The word "recrystallization" is derived from two main components:
1. "Re-" is a prefix of Latin origin, meaning "again" or "backward". In English, it is commonly used to indicate repetition, intensity, or reversal.
2. "Crystallization" is derived from the noun "crystal" and the suffix "-ization". "Crystal" comes from the Greek word "krustallos", which means "ice" or "clear ice". "Crystallization" refers to the process of forming crystals from a solid, liquid, or gas, resulting in a structured and ordered arrangement of atoms or molecules.
Combining these elements, "recrystallization" refers to the process of forming crystals again or anew.
