Water of crystallization in compounds
Water of crystallization refers to water molecules that are bound within the crystal structure of certain compounds. These water molecules are often incorporated into the crystal lattice and are present in a specific ratio to the other components of the compound. The presence of water of crystallization can significantly affect the physical and chemical properties of the compound.
Identifying the compound
In this question, we are asked to identify the compound that exhibits water of crystallization. Let's analyze each option to determine which one fits the criteria.
a) Sodium carbonate (washing soda): Sodium carbonate does not exhibit water of crystallization. It exists as an anhydrous compound, meaning it does not contain water molecules within its crystal structure.
b) Calcium sulfate (gypsum): Calcium sulfate is the correct answer. It exhibits water of crystallization and forms crystals with a specific number of water molecules. The most common form of calcium sulfate with water of crystallization is gypsum, which has the chemical formula CaSO4·2H2O. In this compound, two water molecules are bound to each calcium sulfate molecule.
c) Iron(III) chloride (ferric chloride): Iron(III) chloride does not exhibit water of crystallization. It exists as an anhydrous compound or can form hydrates with a variable number of water molecules.
d) Potassium permanganate: Potassium permanganate does not exhibit water of crystallization. It exists as an anhydrous compound, meaning it does not contain water molecules within its crystal structure.
Conclusion
Among the given options, calcium sulfate (gypsum) is the compound that exhibits water of crystallization, forming crystals with a specific number of water molecules within its structure. This compound is commonly used in construction materials and as a fertilizer.
