What is Crystallization: Definition, Process, Technique, Examples

Answer class9 crystallization is a process which helps to separate a pure solid from a solution in its crystal form. This is the in use to purify solid. For an example the salt we get from seawater can have many impurities in it. Hence, the process of crystallization is in use to remove these impurities. The Solid State.
