Open in App
Solution
The correct option is D Crystallisation
Crystallization is a chemical solid liquid separation technique in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs. The solution is warmed in open container allowing the solvent to evaporate. As the saturated solution is allowed to cool the solid comes out of the solution as crystals and start to grow.
