WebCrystallisation is a separation technique that is used to separate a solid that has dissolved in a liquid and made a solution. The solution is warmed in an open container, allowing the solvent to evaporate, leaving a saturated solution. A solution that has as much solid dissolved in it as it can possibly contain is called a saturated solution. WebOct 20, 2016 · Recrystallisation is defined as “any change in number, size, shape, orientation or perfection of crystals following completion of initial solidification” (Fennema, 1973). 2.1.1.
