Out line the successive steps in the crystallization of an organic solid from a solvent and state the purpose of each operation.

See explanation

Explanation:

Crystallization is a separation technique used to obtain pure crystals of a substance from an impure mixture of solid substances.

The impure solid is dissolved in an appropriate hot solvent. This hot solvent is able to effectively dissolve the solid. However, as the solution is allowed to cool, the pure solid separates out of the solution as crystals.

The solid is now filtered to obtain the pure solid. The solid is also washed and dried to remove any solvent contaminant.
