Definition. Deliquescent: Deliquescent substances are solids that absorb moisture from the atmosphere until they dissolve in the absorbed water and form solutions. Efflorescent: Efflorescent substances are solids that can undergo spontaneous loss of water from hydrated salts.
Which substance is deliquescent?
Deliquescent refers to a property of matter, particularly salt, that is characterized by easy dissolving or melting in water. Typically, hygroscopic substances such as paper, cotton, caramel, sulfuric acid, chemicals, fertilizer and common table salt are considered deliquescent.
What is the difference between hygroscopic and deliquescent?
Hygroscopic and deliquescent materials both can absorb moisture from the air. But, hygroscopy and deliquescence are not the same things: Hygroscopic materials absorb moisture On the other hand deliquescent materials absorb moisture to the extent that the substance dissolves in water.
What is deliquescent give examples?
Answer : Compounds that take up enough water from the air to dissolve in the water they have taken up are called deliquescent. Calcium chloride (CaCl2) and Sodium hydroxide (NaOH) are the examples of deliquescent.
What is an Hydroscopic substance?
A hygroscopic substance is one that readily attracts water from its surroundings, through either absorption or adsorption. Examples include honey, glycerin, ethanol, methanol, concentrated sulfuric acid, and concentrated sodium hydroxide (lye).
What is hygroscopic chemistry?
A hygroscopic material (literally water seeking) is one that readily absorbs water (usually from the atmosphere). In most cases, the water can be removed from the material by heating (sometimes under vacuum or under a flow of dry gas such as nitrogen).
What does Hydroscopic mean?

What is difference between efflorescence and Deliquescence?
Let us look the definitions of each terms, Efflorescence refers to the action of movement of salty liquids to the surface of a porous material, where the liquid evaporates leaving a white powdery coating on the surface and Deliquescence is the process by which a chemical substance absorbs moisture from the …

Why are things hygroscopic?
A hygroscopic substance is one that readily attracts water from its surroundings, through either absorption or adsorption. … Calcium chloride is so hygroscopic that it eventually dissolves in the water it absorbs: this property is called deliquescence.
What is Deliquescent chemistry?
Deliquescence, the process by which a substance absorbs moisture from the atmosphere until it dissolves in the absorbed water and forms a solution. Deliquescence occurs when the vapour pressure of the solution that is formed is less than the partial pressure of water vapour in the air.

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
