The technique used to separate and collect a soluble solid from a solution is called crystallisation.
Explanation of Crystallisation
- Crystallisation involves heating the solution to evaporate some of the solvent, resulting in a saturated solution. As the solution cools, the solubility of the solid decreases and crystals begin to form.
- These crystals can then be collected by filtration, washed with distilled water to remove impurities, and dried to obtain the pure soluble solid.
- This method works because the solid is more soluble in the hot solvent than in the cold, allowing controlled crystallisation upon cooling.
This technique is commonly used in chemistry to separate dissolved solids like salts from their solutions effectively.
