Define the terms
(i) Deliquescence
(ii) Efflorescence
(iii)Water of crystallization
(iv)Hygroscopy
(v) Anhydrous substance
Answers
Explanation:
Hygroscopic absorbs water and becomes clumpy.
Deliquescent absorbs water and dissolves into it (becomes liquid)
Almost all soluble salts are deliquescent.
Sugar is a good hygroscopic material.
Deliquescent is a degree of hygroscopic properties.
A hygroscopic substance absorbs water from the atmosphere. It may absorb enough to clump together, but that’s it. A deliquescent substance absorbs so much water from the atmosphere that it actually forms a liquid.
Answer...
1. Deliquescence, the process by which a substance absorbs moisture from the atmosphere until it dissolves in the absorbed water and forms a solution.
2. Efflorescence, spontaneous loss of water by a hydrated salt, which occurs when the aqueous vapor pressure of the hydrate is greater than the partial pressure of the water vapor in the air.
3. water of crystallization" refers to water that is found in the crystalline framework of a metal complex or a salt, which is not directly bonded to the metal cation.
4. Hygroscopy is the phenomenon of attracting and holding water molecules via either absorption or adsorption from the surrounding environment, which is usually at normal or room temperature.
5. Anhydrous substance are chemical compounds that have no water molecules in the chemical structure. ... Anhydrous compounds are known as anhydrates.
