Deliquescent materials are sufficiently hygroscopic that they dissolve in the water they absorb, forming an aqueous solution. Hygroscopy is essential for many plant and animal species' attainment of hydration, nutrition, reproduction and/or seed dispersal .
Primary efflorescence is named such, as it typically occurs during the initial cure of a cementitious product. It often occurs on masonry construction, particularly brick, as well as some firestop mortars, when water moving through a wall or other structure, or water being driven out as a result of the heat of hydration as cement stone is being formed, brings salts to the surface that are not ...
The following compounds are liquid at room temperature and are completely miscible with water; ... Many of them are hygroscopic. Organic compounds ... C 4 H 10 O 2 ...
4 and two molecules of water of crystallization. [8] This species dissolves readily in water and alcohol. The anhydrous salt is hygroscopic and the hexahydrate is deliquescent. [citation needed] The dihydrate, CoCl 2 (H 2 O) 2, is a coordination polymer. Each Co center is coordinated to four doubly bridging chloride ligands.
The selection of hygroscopic salts have to provide the following strict criteria in order to be of interest of use in the hygroscopic cycle: Highly hygroscopic compounds, deliquescent materials; Less volatile than water (vapor pressure lower than water), with easily reversible desorption into water and steam in the boiler
Secondly, Dessication has very little to do with Deliquescence, in spite of how many deliquescent materials are use for dessication. Dessication is a process for removing water; Deliquescence is a property of certain molecules. Merging would just provide confusion to viewers of the encyclopedia.
