This is the second blog post in a series dedicated to crystallization. In case you missed the first in the series, you can find it here: Introduction to Crystallization and Precipitation.
The starting point for most crystallization processes is a saturated solution. Crystallization is generally achieved by reducing the solubility of the product in this solution by cooling, antisolvent addition, evaporation* or some combination of these methods. Another common method used to drive crystallization is via a chemical reaction where two or more reactants are mixed to form a solid product insoluble in the reaction mixture; a common example of this would be the reaction of an acid and a base to form a salt.
