Salt can be recovered from its solution by evaporation. Another technique which can be used for the separation of a salt from its solution is :
The correct option is D crystallization
Crystallization can be used for separation of a salt from its solution. 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.
