#Crystallization #Chemistry #AbdullahSanaullahTutorials Crystallization is used to prepare pure crystals of a crude substance. Crystallization is very common method of purification of organic compound. Impure compound is dissolved in solvent, in which it is more soluble. Concentrate the solution by continuous heating, until the solution reaches to its saturation point. However, even after the formation of crystal some amount of solution is left, known as mother liquor. Crystals are separated. It is interesting to know that, if compound is highly soluble in one solvent and less soluble in another, then crystallization can be done by mixing both the solvents. However, impurities that impart color to solution are removed by adsorbing over an activated charcoal.
