Crystallisation class 6
WebCrystallisation. Crystallisation is a process of separation of solid from a liquid in which it has dissolved earlier and made a solution. It is the slow precipitation of crystals from a saturated solution. The solution is warmed in an open container, allowing the solvent to evaporate, leaving a saturated solution. WebCrystallization is a process by which a pure soluble substance separates out in the form of crystals from its hot and saturated solution on cooling. The process is employed in the separation of pure common salt from the impure common salt obtained from sea. Similarly, it is used to obtain pure nitre from impure nitre (KNO 3) pure copper ...
