Crystallization is used to purify a solid. The process requires a suitable solvent. Asuitable solvent is one which readily dissolves the solid (solute) when the solvent is hotbut not when it is cold. The best solvents exhibit a large difference in solubility over areasonable range of temperatures. (eg, Water can be a Crystallization solvent between0-100oC; hydrocarbon solvents such as hexanes or petroleum ether have a different Trange since they can be cooled below 0 degrees but boil below 100 degrees). Characteristics of a solvent:a. chosen for solubilizing power-- solubility usually increases with increasing Tb.
