What is the difference between efflorescent and hygroscopic?
Efflorescent substances (e.g. sodium carbonate decahydrate, copper(II) sulfate pentahydrate) lose some or all of their water of crystallisation when exposed to the air. Hygroscopic substances (e.g. concentrated sulphuric acid, calcium oxide) absorb water from the atmosphere but do not dissolve in it.
What is the difference between deliquescence and efflorescence?
Deliquescence is the process in which a substance absorbs moisture from the air until it dissolves in the absorbed water, forming a solution. Efflorescence, on the other hand, occurs when a substance loses water of crystallization and forms a powdery deposit on the surface as the water evaporates.
What are the examples of efflorescent substances?
Efflorescence refers to the process where wet particles decrease in size through losing water to eventually crystallize out. An example of an efflorescent substance is the common Copper(II) sulfate crystal (CuSO4.5H2O), a blue crystalline solid that when exposed to air, slowly loses water of crystallization from its surface to crystallise to form a white layer of anhydrous copper(II) sulfate.
What is a substance dissolve in another substance called?
A substance that dissolves in another substance is called a solute.
What is the possessive form of the word substance?
The possessive form for the noun substance is substance's.Example: The substance's origin could not be determined.
What are the example of efflorescent and deliquescent substance?
efflorescent- washing soda, copper sulphate, glauber salt deliquescent -calcium chloride, sodium hydroxide, iron3 chloride
What is effloroscent?
Efflorescent refers to a substance that loses moisture and forms a powdery deposit on its surface. This phenomenon often occurs in salts and minerals when they are exposed to air.
What is a efflorescent?
A state or time of flowering

What is the difference between deliquesent and efflorescent compounds?
efflorescent substances are substances which looses moisture partly or completely to the atmosphere and changes in to amorphous powder. deliquecent substances are substances which absorb moisture from the atmosphere and turn into a saturated solution.
Is potassium hydroxide hygroscopic efflorescent or deliquescent?
Potassium hydroxide is hygroscopic and deliquescent.
Is their any sodium mono sulfate?
No. There is no such compound. Apart from sodium sulphate, there is Sodium thiosulfate.Sodium thiosulfate (Na2S2O3)s a colorless crystalline compound that is more familiar as the pentahydrate, Na2S2O3•5H2O, an efflorescent, monoclinic crystalline substance also called sodium hyposulfite or "hypo.

Why may a stored sample of Na2CO3.10H2O contain less water than a sample that was not stored?
Sodium carbonate decahydrate, Na2CO3.10H2O readily loses some of the water of crystallisation eventually forming the monohydrate. It is an efflorescent salt, and its composition will change with time.
What does efflorescent means?
In Chemistry:The deposit that results from the process of efflorescing. Also called bloomA growth of salt crystals on a surface caused by evaporation of salt-laden water.In Botany:A gradual process of unfolding or developing.OrThe highest point; the culmination.In Pathology:Redness, Rash, or and eruption on the skin.
