- To remove dissolved impurities (correct)
- To cool down the solution
- To speed up the crystallization process
- To increase the solubility of the solute
Why is a saturated solution of the crude solid prepared in the crystallization process?
Why is a saturated solution of the crude solid prepared in the crystallization process?
- To prevent the addition of more solute (correct)
- To ensure a higher yield of crystals
- To allow for easier filtration
- To make sure all impurities dissolve
