Question

What do you observe in the china dish during crystallization?

Answer 1

Hint: The answer here is based on the fact of the principle of crystallization that is the process that takes place when an impure substance is dissolved in a minimum amount of water in a china dish. This reaction leads you to the correct answer.

Complete Solution :
The concepts of several laboratory processes used for the synthesis of new compounds are familiar to us where the process includes crystallisation also.
- Let us go through the process of crystallization about how it takes place and what is obtained from it.
We are all familiar with using china dishes in the laboratories for heating the mixture of chemicals in it.
The process of crystallisation is also done in this.
- Crystallisation is the process of producing the crystals in which the atoms or molecules are highly organized into a structure which is nothing but crystals.
- The process of this crystallisation is doer in the china dish composed of porcelain that involves dissolving the impure substances in minimal amount of water that is followed by the filtration and finally the water is evaporated which leaves the saturated solution behind and when this solution is left undisturbed, we get pure crystals.
Thus, the correct answer is when crystallisation is carried in a china dish we get pure crystals of the substance.

Note: Note that china dish and petri dish are different names and do not symbolise the same thing. China dish is a round bottomed crucible shaped dish which is made of porcelain used for the chemical reactions and petri dish is flattened glass dish which is used basically for the culture of microorganisms.
