A process in which a hot saturated solution of salt on cooling gives crystals is called
Answers
Answer:
crystallization is the process
Crystallisation Process
Crystallisation process results in a physical change in objects. It leads to the formation of crystal structures. Clear distinguish between processes of crystallisation is not possible. But we can identify two categories of crystallisation processes namely Cooling Crystallisation and Evaporative Crystallisation.
Cooling Crystallisation
Many substances, when dissolved in solvent, form crystals on cooling in favorable conditions in this process. However, this method is not very common and has many limitations. Usually, the substance is heated and then allowed to cool down in this method.
Evaporative Crystallisation
It is more common than cooling crystallisation. Evaporating sea water leaves salt behind. Pure Crystals of Substance are deposited after evaporation of solutions. But this method requires a high concentration of the substance in the solution. Therefore, its solute/solvent mass ratio should be high.
