Efflorescence

Efflorescence Definition •    The spontaneous dehydration of a compound is called Efflorescence. •    The loss of water of crystallization by a hydrated (crystalline substance with water of crystallization )to form anhydrous salts or hydrated with less molecules of water of crystallization is called Efflorescence. The large no of chemical compound exists in hydrated or anhydrous form. In hydrated form the water molecule attached to the compound are called the water of crystallization. The surrounding atmosphere also has vapours and definite vapour pressure, due to water in atmosphere. If the vapour pressure of the hydrated substance is greater than the surrounding atmosphere, than the hydrated substance loses water molecule to become less hydrous and to make an equilibrium between the hydrated substance and the atmosphere. Efflorescence, spontaneous loss of water by a hydrated salt, which occurs when the aqueous vapor pressure of materials is gre...
