Magnesium chloride hexahydrate (MgCl₂·6H₂O) is a hydrated inorganic salt with six water molecules coordinated to each magnesium chloride unit. It presents as colorless or white deliquescent crystals, bitter in taste, with a density of 1.57 g/cm³ and marked hygroscopicity that demands sealed storage.

The compound exhibits strong moisture affinity, liquefying in humid air above 32% relative humidity. It dissolves exothermically in water, releasing 155 kJ/mol-solutions reach 50°C undisturbed from room temperature. Dehydration proceeds through distinct stages: tetrahydrate at 100°C, dihydrate near 185°C, with full anhydrous conversion requiring 300°C and HCl atmosphere to prevent hydrolysis.

Its applications leverage these properties directly. Dust control crews in Colorado spray 32% solutions onto gravel roads; magnesium chloride binds surface particles, suppressing particulate matter without the corrosive damage of calcium chloride. Japanese tofu makers dissolve nigari-traditional bittern derived from seawater evaporation-where magnesium ions coagulate soy protein into silken curds. De-icing operations favor it for airport runways, effective to −23°C with less concrete spalling than rock salt. Metallurgical furnaces consume anhydrous grades as molten electrolyte for primary magnesium production, the hexahydrate serving as precursor through controlled dehydration.

Storage demands attention. Bulk hexahydrate cakes irreversibly when exposed; poly-lined containers with desiccant maintain flowability through tropical transit.

Application

Magnesium chloride hexahydrate is a versatile compound with many everyday uses. On roads, it effectively controls dust and melts ice. In agriculture, it provides essential magnesium to enrich soil and help plants grow. It is also a key ingredient in the production of tofu, giving it a smooth and firm texture. Furthermore, this mineral is crucial in manufacturing various magnesium-based products, including supplements that support human health. Its ability to absorb moisture from the air makes it useful in some de-icing and drying processes as well.
