The deliquescence is a property in which a solid____________________?
Correct answer: B. Absorbs moisture and turns to liquid form
- A. Absorbs moisture and remains solid
- B. Absorbs moisture and turns to liquid form
- C. Loses water of crystallization
- D. Increases the number of water of crystallization
Explanation
A deliquescent solid absorbs water vapour from the air until it dissolves in the absorbed water and becomes liquid. This differs from an efflorescent solid, which loses water of crystallization. Students commonly choose a by confusing deliquescence with ordinary moisture absorption without liquefaction.

About Crystalline Solids
Crystalline solids contain particles arranged in a regular repeating lattice described by a unit cell. Their study includes coordination number, packing efficiency, density, anisotropy, cleavage, polymorphism and common crystal systems, along with ionic, molecular, covalent network and metallic crystals. Crystalline order differs from the random arrangement of amorphous solids.
