Magnesium sulfate or magnesium sulphate is a chemical compound, a salt with the formula MgSO 4, consisting of magnesium cations Mg 2+ (20.19% by mass) and sulfate anions SO 2− 4. It is a white crystalline solid , soluble in water but not in ethanol .
Magnesium sulfate was historically used as a treatment for lead poisoning. Prior to the development of chelation therapy , cases of accidental lead ingestion were often immediately treated with magnesium sulfate, which would cause the lead to be precipitated out and, with a high enough dose, literally purged from the digestive system as ...
As a bronchodilator after beta-agonist and anticholinergic agents have been tried, e.g. in severe exacerbations of asthma. [4]Obstetrics: Magnesium sulfate is used to prevent seizures in women with preeclampsia and eclampsia, and is also used for fetal neuroprotection in preterm deliveries, but has been shown to be an ineffective tocolytic agent.
Sodium magnesium sulfate is a double sulfate of sodium and magnesium. There are a number of different stoichiometries and degrees of hydration with different crystal structures, and many are minerals. Members include: Blödite or bloedite: sodium magnesium sulfate tetrahydrate Na 2 Mg(SO 4) 2 •4H 2 O [1]
Typically anhydrous solvents will contain approximately 10 ppm of water and will increase in wetness if they are not properly stored. Organic solutions can be dried using a range of drying agents. Typically following a workup the organic extract is dried using magnesium sulfate or a similar drying agent to remove most remaining water. [5]
In 1990, the safety of synthetic magnesium silicate was reviewed by the Scientific Committee on Food (SCF) together with that of silica and the other metal alkali silicates. [10] The SCF noted that “the available data, including a number of short-term studies in two species, appear to substantiate the biological inertness of those compounds”.
Epsomite, Epsom salt, or magnesium sulfate heptahydrate, is a hydrous magnesium sulfate mineral with formula MgSO 4 ·7H 2 O. Physical properties
Magnesium salicylate is a common analgesic [1] and nonsteroidal anti-inflammatory drug (NSAID) [2] used to treat mild to moderate musculoskeletal pain [3] such as in tendons and muscles. [ citation needed ] It is also used to treat joint pain like arthritis , [ 2 ] [ 3 ] general back pain , [ 4 ] and headaches .
