Solution crystallization

WebRecrystallization is a technique used to purify solid compounds. 1 Solids tend to be more soluble in hot liquids than in cold liquids. During recrystallization, an impure solid compound is dissolved in a hot liquid until the solution is saturated, and then the liquid is allowed to cool. 2 The compound should then form relatively pure crystals. WebIf a saturated solution containing 45 g of product per 100 g solvent A is cooled from 50 °C to 20 °C, then 15 g of product per 100 g of solvent will remain in solution. Therefore, 30 g of product should crystallize, allowing …
