Physical chemistry

A solid pulls in water and dissolves itself

Deliquescence is the process by which a water-soluble solid absorbs moisture from the air until it takes up enough to dissolve into a saturated solution of itself. It happens once the surrounding humidity passes a material-specific threshold, the deliquescence relative humidity, above which the vapour pressure over the forming solution is lower than that of the air, so water keeps condensing in. Mauer and Taylor's 2010 review Water-Solids Interactions: Deliquescence sets out the phenomenon and its consequences for the stability of powders and crystalline materials. The referent is a solid dissolving by scavenging atmospheric water, a behaviour of hygroscopic salts and sugars.[1]

Unit
The deliquescence relative humidity at which the solid begins to dissolve in absorbed water
Recovery means
Not applicable
Measured by
Determined by the deliquescence relative humidity from moisture-sorption isotherms and by water-uptake measurements at controlled humidity
