Crystallization
Crystallization
The process of evaporation gives only the residue which may contain some impurities. To obtain the solid free from impurities the method of crystallization is used. For this, the solution is taken in a china dish and evaporated on a water bath till the solution becomes saturated. To check whether the saturation point has reached or not, take some solution on a glass rod and cool it. At the point of saturation, solid particles in regular and definite shape begin to appear. These particles are called crystals.
The saturated solution is removed from the flame and allowed to cool to the room temperature. The crystals of the solid separate from the solution. The process is called crystallization. The crystals are then filtered out. Thus, the process by which a pure solid in the form of crystals separates from a solution is called crystallization. Hence, the process of crystallization is used to purify solids.
