What is crystallisation
Answers
Crystallization is a process that separates a pure solid in the form of its crystals from a solution. This method is used to purify solid, example the salt we get from sea water can have many impurities in it. To remove these impurities, the process of crystallization is used.
The most frequently applied types of crystallization are: Evaporative crystallization. Cooling crystallization from solution or the melt. Reactive crystallization or precipitation.
Crystallization is used in the chemistry laboratory as a purification technique for solids. An impure solid is completely dissolved in a minimal amount of hot, boiling solvent, and the hot solution is allowed to slowly cool.
Answer:
Ur answer:
The process of deriving large crystals of pure substances from their solutions is known as crystallisation.
It is a physical change.
Crystals of salt are obtained by the evaporation of sea water.
