Answer: The given statement is true.
Step-by-step explanation:
Crystallization is defined as a process in which an impure solid substance is purified with the help of heating.
In this process, impure solid is dissolved in a solvent and then this solution is made to boil. After that, the solution is cooled down and solid begins to appear as pure crystals.
Then, crystals can be collected on a filter paper or they can be collected through decantation process.
Hence, we can conclude that crystallization is a good way to purify solids.
