WebOct 5, 2016 · The goal of recrystallisation is to obtain purified crystals from impure solid, as much as possible. The solute is therefore dissolved in a solvent where the solubility is high at the boiling point, but low (or insoluble) at the room temperature. Additionally the impurities should be soluble in the solvent at room temperature. the notebook grossWebProcess of Recrystallization 1. Find a suitable solvent for the recrystallization; 2.
