Deliquescence is 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.
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 octahedron is completed by a pair of mutually trans aquo ligands. [9]
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
Hygroscopic is a property of a substance to absorb or adsorb water from its surrounding (one example of this would be dessicator type of compounds). [2] And finally in this volume of scientific american they seem to refer to a hygroscope as an instrument measuring if there is water in the air & a hygrometer as an instrument which quantifies the ...

Sodium thiocyanate crystallizes in an orthorhombic cell. Each Na + center is surrounded by three sulfur and three nitrogen ligands provided by the triatomic thiocyanate anion. [ 3 ] It is commonly used in the laboratory as a test for the presence of Fe 3+ ions .
