It is often encountered as the heptahydrate sulfate mineral epsomite (MgSO 4 ·7H 2 O), commonly called Epsom salt.

Epsomite

Magnesium sulfatemagnesium sulfate heptahydrate
It is often encountered as the heptahydrate sulfate mineral epsomite (MgSO 4 ·7H 2 O), commonly called Epsom salt.
Epsomite is a hydrous magnesium sulfate mineral with formula MgSO 4 ·7H 2 O.

Epsom

Epsom, SurreyEpsom, EnglandHorton
Epsom salt takes its name from a bitter saline spring in Epsom in Surrey, England, where the salt was produced from the springs that arise where the porous chalk of the North Downs meets non-porous London clay.
The town also gives its name to Epsom salts, originally extracted from mineral waters there.

Kieserite

The monohydrate, MgSO 4 ·H 2 O is found as the mineral kieserite.
Kieserite is the magnesium sulfate mineral (MgSO 4 ·H 2 O) and is named after Dietrich Georg von Kieser (Jena, Germany 1862).

Bath salts

bath saltbath oilbath beads
Epsom salt has been traditionally used as a component of bath salts. Epsom salt is used as bath salts and for isolation tanks.
Substances often labeled as bath salts include magnesium sulfate (Epsom salts), sodium chloride (table salt), sodium bicarbonate (baking soda), sodium hexametaphosphate (Calgon, amorphous/glassy sodium metaphosphate), sodium sesquicarbonate, borax, and sodium citrate.

Salt (chemistry)

saltsaltspotassium salt
Magnesium sulfate is an inorganic salt with the formula MgSO 4 (H 2 O) x where 0≤x≤7.
Different salts can elicit all five basic tastes, e.g., salty (sodium chloride), sweet (lead diacetate, which will cause lead poisoning if ingested), sour (potassium bitartrate), bitter (magnesium sulfate), and umami or savory (monosodium glutamate).

Isolation tank

Epsom salt is used as bath salts and for isolation tanks.
The tank is filled with 10 inches of water which contains enough dissolved Epsom salt to create a specific gravity of approximately 1.275.

Salts are compounds like sodium chloride, magnesium sulfate, potassium nitrate, and sodium bicarbonate which dissolve into ions.

Magnesium sulfate (medical use)

Magnesium sulfate is the main preparation of intravenous magnesium.
As epsom salts, it is also used for mineral baths.

Asthma

Magnesium (medical use)

Magnesium (pharmaceutical preparation)magnesium preparationmagnesium supplementation
Magnesium sulfate is a common mineral pharmaceutical preparation of magnesium, commonly known as Epsom salt, used both externally and internally.
An exception is the administration of magnesium sulfate in barium chloride poisoning, where sulfate binds to barium to form insoluble barium sulfate.

Diazepam is used for the emergency treatment of eclampsia, when IV magnesium sulfate and blood-pressure control measures have failed.

Tofu

It may also be used as a coagulant for making tofu.
It is high in iron, and can have a high calcium or magnesium content depending on the coagulants (e.g. calcium chloride, calcium sulfate, magnesium sulfate) used in manufacturing.

In agriculture, magnesium sulfate is used to increase magnesium or sulfur content in soil.

Meridianiite

Both are, however, not the highest known hydrates of MgSO 4, due to the recent terrestrial find of meridianiite, MgSO 4 ·11H 2 O, which is thought to also occur on Mars.
Meridianiite — MgSO 4 •11H 2 O — is the crystalline 11-hydrate magnesium sulfate phase that precipitates from solutions saturated in Mg 2+ and SO 4 2− ions at temperatures less than 2 ˚C.

Treatment is directed towards the withdrawal of the offending agent, infusion of magnesium sulfate, and electrical therapy, such as a temporary pacemaker, as needed.

Anhydrous

waterlessfree from the presence of water
Anhydrous magnesium sulfate is commonly used as a desiccant in organic synthesis due to its affinity for water and compatibility with most organic compounds.
Typically following a workup the organic extract is dried using magnesium sulfate or a similar drying agent to remove most remaining water.

Occator (crater)

OccatorOccator crater
Bright spots observed by the Dawn Spacecraft in Occator Crater on the dwarf planet Ceres are most consistent with reflected light from magnesium sulfate hexahydrate.
On 9 December 2015, scientists reported that the bright spots on Ceres, including those in Occator, may be related to a type of salt, particularly a form of brine containing magnesium sulfate hexahydrite (MgSO 4 ·6H 2 O); the spots were also found to be associated with ammonia-rich clays.

Sodium sulfate

Other inorganic sulfate salts such as sodium sulfate and calcium sulfate may be used in the same way.
In the laboratory it can also be synthesized from the reaction between sodium bicarbonate and magnesium sulfate.
