Solution
Crystallization is the process of forming solid crystals from a liquid.
The solvents evaporate when the solution warms, leaving a more pure product in a form of pure solute.
Impure salt gets dissolved in a suitable solvent in this process.
Some contaminants will remain undissolved after pure salt particles have dissolved.
The pure salt is then obtained by recrystallizing the residual solution. As a result of the crystallization process. Procedure: Filter the solution to remove contaminants and undissolved salt from the dissolved pure salt.
Allow time for it to cool. While the solution is cooling, do not disturb it.
After some time, pure salt crystals will develop in the solution, and the crystals will begin to grow.
