deliquescence The absorption of atmospheric moisture by a solid until it dissolves to form a saturated solution. If it merely forms a crystalline hydrate it is termed hygroscopic. The phenomenon depends on the relative humidity: sugar, for example, deliquesces above 85% humidity. See also efflorescence.
