Question

The process of forming large crystals of pure substances from their solutions is known as:
A.Evaporation
B.Purification
C.Condensation
D.Crystallization

Answer 1

Crystallization is the solidification of atoms or molecules into a highly structured form called a crystal. Usually, this refers to the slow precipitation of crystals from a solution of crystals from a solution of a substance. Crystals can form from pure melt or directly from decomposition from the gas phase. Crystallization can refer to the solid-liquid separation and purification technique in which mass transfer occurs from the liquid solution to a pure solid crystalline phase.
Complete step by step answer:
The process of forming large crystals of pure substances from their solutions is known as crystallization. The thermodynamic conditions of crystallization and kinetics of crystals nucleation and growth is concerned with the principle of crystallization.
There are different types of crystallization:
A.Evaporation crystallization
B.Cooling crystallization from solution or melt
C.Reactive crystallization or precipitation.
Above crystallization method happens in different conditions by different processes.

Thus, Option (D) is the correct answer.

Additional information:
Crystallization is the process of atoms or molecules arranging into a well-defined, rigid crystal lattice in order to minimize their energetic state. The crystallization process forms large crystals in pure substance.

Note: Crystallization process in solid crystals are formed from another phase, typically a liquid solution or melt. To crystallize an impure, solid compound, add just enough hot solvent to it to completely dissolve it. Crystallization is the physical transformation of a liquid, or a gas to a crystal which is a solid with an ordered internal arrangement of molecules, ions or atoms.
