Answer 1

$\mathfrak{\huge{\orange{\underline{\underline{Answer :}}}}}$

Crystallization is a technique used for the purification of substances. A separation technique to separate solids from a solution.

Crystallization Process

1. The solution is heated in an open container

2. The solvent molecules start evaporating, leaving behind the solutes

3. When the solution cools, crystals of solute start accumulating on the surface of the solution

4. Crystals are collected and dried as per the product requirement

5. The undissolved solids in the liquid are separated by the process of filtration

6. The size of crystals formed during this process depends on the cooling rate.

7. A large number of tiny crystals are formed if the solution is cooled at a fast rate

8. Large crystals are formed at slow cooling rates
