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 .
In the United Kingdom, a medication containing magnesium sulfate, called "drawing paste", is claimed to be useful for small boils or localised infections, [19] and removing splinters. [20] The standard British Pharmacopoeia composition is dried magnesium sulfate 47.76% (by mass), phenol 0.49%, and glycerol to balance. [19]
In the laboratory, anhydrous sodium sulfate is widely used as an inert drying agent, for removing traces of water from organic solutions. [26] It is more efficient, but slower-acting, than the similar agent magnesium sulfate. It is only effective below about 30 °C (86 °F), but it can be used with a variety of materials since it is chemically ...
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]
Meridianiite is the mineral consisting of magnesium sulfate undecahydrate, MgSO 4 ·11H 2 O.It is colorless transparent crystalline salt that precipitates from solutions saturated in Mg 2+ and SO 4 2− ions at temperatures less than 2 °C. [4]
The only mention of magnesium sulfate/bath salts/epsom salts is the phrase "Magnesium sulfate is said to be a good natural cure for boils." Unless someone can provide a proper citation, this segment should either be removed, or altered to make it clear that it is a "folk cure".
Magnesium acetate is a relatively safe compound to handle and has been given a health hazard rating of zero. However, it should always be handled with gloves and safety goggles. If it gets in the eyes, the skin, ingested, or inhaled it will cause irritation in the respective areas: eyes, skin, gastrointestinal system, and lungs.
