Crystallization
Q1: What is the Definition of Crystallization?
Answer:
Crystallization is a process that happens when the materials solidify from a liquid, in this process, the molecules of the solute dissolved in the liquid combined together to form a crystal.
Q2: What is the Water of Crystallization?
Answer:
The fixed amount of water associated with hydrated crystals that is an integral part of the crystal is known as the water of crystallisation.
Example: In Blue Vitriol CuSO4.5H2O, the water of crystallization is 5 and in Glauber Salt Na2SO4.10H2O the water of crystallisation is 10.
Q3: What is a Decahydrate Crystalline Salt?
Answer:
Washing Soda is a decahydrate crystalline salt. Its molecular structure is (Na2CO3.10H2O) as we see it has 10 water molecules and hence its name is decahydrate.
Q4: What are the Advantages of Crystallization?
Answer:
The key advantages of crystallization are listed below.
- A product of high purity can be obtained from one single step via the process of crystallization.
- The dry products formed from crystallization can be directly packaged and stored.
- The energy requirements and the operating temperatures of this process are relatively low.
Q5: What is the Crystallization Point?
Answer:
The temperature at which the crystallization of the solid starts, i.e. its nucleus begins to form is called the crystallization point.
Q6: What are some Examples of Crystallization?
Answer:
- Crystallization of water to form ice cubes
- Crystallization of honey placed in a jar
- Formation of stalagmites and stalactites
Q7: What happens when Benzoic Acid Crystals are heated individually?
Answer:
When benzoic acid crystals are heated individually, they undergo sublimation.
Crystallization
Crystallization is a technique for purification of the substances. It is a technique that separates a solid from its solution. The process in which the solid dissolve in the liquid arranges itself in well-defined 3-D structures called the crystal is called crystallization. When any substance undergoes crystallization its molecule arranges itself in a fixed structure at an angle to form a 3-D structure called the crystal and then the crystal is removed from the solution. The crystal is a pure substance and thus the process of crystalization is widely used in the purification of material from its impure solution.
In this article, we will learn about crystallization, the process used for crystallization, its example, and its application in detail in this article.
