The incorporation of molecular water into a complex with the molecules or units of another species. The complex may be held together by relatively weak forces or may exist as a definite compound. Many salts form solid hydrates when exposed to water vapor under certain conditions of temperature and pressure. Water is lost from these compounds when they are heated or when the water vapor pressure falls below a minimum value. Solids forming hydrates at low pressures are used as drying agents. See also Deliquescence; Desiccant; Efflorescence; Hydrate; Solution; Solvation.

hydration
The incorporation of water by minerals. Hydration often causes swelling and is believed to be a major cause of the crumbling of coarse-grained igneous rocks which are disrupted by the expansion of their hydrated minerals. Compare with hydrolysis.
