Recrystallization for Solid Compound Purity
Description
Recrystallization is a technique for purifying solid compounds. It uses the fact that solids are often more soluble in hot liquids than in cold liquids. An impure solid is dissolved in a hot liquid until the solution becomes saturated, meaning it holds as much dissolved material as it can at that temperature.

La recristallisation est une technique de purification des composés solides.
Pour effectuer la recristallisation, un composé solide impur est mélangé à un solvant chaud pour former une solution saturée. Au fur et à mesure que cette solution refroidit, la solubilité du composé diminue et des cristaux purs se développent à partir de la solu...
