Solution

Correct Answer:

To remove insoluble impurities before crystal formation

During recrystallization, the impure solid is dissolved in hot solvent and then hot filtration is done to remove insoluble impurities (like dust or charcoal). On cooling, pure compound crystallizes out while soluble impurities remain in mother liquor.

This easy difficulty chemistry question is from the chapter principles related to practical chemistry, covering the topic of purification by crystallization. It appeared in the 2025 exam.
