Question

Explain the process of crystallisation with steps

Answer 1

Crystallisation is a separation technique that is used to separate a solid that has dissolved in a liquid and made a solution.

• The solution is warmed in an open container, allowing the solvent to evaporate, leaving a saturated solution.
• A solution that has as much solid dissolved in it as it can possibly contain is called a saturated solution.
• As the saturated solution is allowed to cool, the solid will come out of the solution and crystals will start to grow.
• The crystals can then be collected and allowed to dry.
