Example to show crystallization--to obtain pure copper sulphate from an impure sample. 1- Take 5 gm of impure sample of copper sulphate in a china dish. 2- Dissolve the sample in minimum 10ml of water to prepare a saturated solution. 3- Filter it to remove impurities 4- Evaporate the filtrate on...

It will be observed that crystals of pure copper sulphate are obtained and impurities are left behind in the solution. read less

It is the process of converting impure substance in its pure crystal form. It is based on different solubilities of a compound and its impurities in a suitable solvent. We add water to the impure sample and then warm so as to obtain a saturated solution which is later cooled. By this crystal of pure...

Crystallization separates a product from a liquid feedstream, often in extremely pure form, by cooling the feedstream or adding precipitants which lower the solubility of the desired product so that it forms crystals.

Crystallization separates a product from a liquid feedstream, often in extremely pure form, by cooling the feedstream or adding precipitants which lower the solubility of the desired product so that it forms crystals. Well formed crystals are expected to be pure because each molecule or ion must fit perfectly into the lattice as it leaves the solution. Impurities would normally not fit as well in the lattice, and thus remain in solution preferentially. Hence, molecular recognition is the principle of purification in crystallization. However, there are instances when impurities incorporate into the lattice, hence, decreasing the level of purity of the final crystal product. Also, in some cases, the solvent may incorporate into the lattice forming a solvate. In addition, the solvent may be 'trapped' (in liquid state) within the crystal formed, and this phenomenon is known as "inclusion". read less
