Question

What is crystallization?How is better than evaporation. (point 5)
​

Answer 1

Crystallisation

Crystallisation or crystallisation is the process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some of the ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas.

Types Of Crystallization

• Evaporative crystallization.
• Cooling crystallization from solution or the melt.
• Reactive crystallization or precipitation.

Answer 2

Answer:

Crystallisation is a process that separates a pure solid in the form of its crystals from a solution. Crystallisation is better than evaporation because during Evaporation. Some solids decompose or some, like sugar, may get charred on heating to dryness. In such cases, the crystallisation technique is applied.
