What is Fractional Crystallization of Salts?

Fractional crystallization of salts is a separation technique that exploits the differences in solubility between various salts (or between a salt and other dissolved substances) in a particular solvent. The process hinges on the fact that as the temperature of a solution changes, or as the solvent evaporates, the solubility of dissolved salts changes. Typically, as a solution cools, the solubility of most solid salts decreases, causing the least soluble salt to precipitate out first in crystalline form. This technique is called
