Beschreibung
In addition to its use in foods as a flavor enhancer, nutrient supplement and processing aid, magnesium sulfate (as Epsom salt) is employed in over-the-counter preparations as a laxative. As a legend (prescription drug) it has been used as an anticonvulsant and electrolyte replenisher.
Chemische Eigenschaften
White or almost white, crystalline powder or brilliant, colourless crystals.
Verwenden
Magnesium sulfate heptahydrate has been used:
- as a component in Kreb′s Ringer buffer
- as a component in minimal medium to culture Ralstonia solanacearum
- in the preparation of maceration solution for Lamb′s lettuce cell isolation and isotonic glucose buffer
Verwenden
Magnesium Sulfate is a nutrient and dietary supplement. It is soluble in water and its solutions are neutral. It exists as crystals with a cooling, saline, bitter taste. It is also termed epsom salt.
Verwenden
Used in preparation of magnesium standard solutions
Definition
Epsomite: a mineral form of magnesiumsulphate heptahydrate,MgSO₄.7H₂O.
Allgemeine Beschreibung
Magnesium sulfate heptahydrate is hydroscopic and is vulnerable to warm temperatures.
Landwirtschaftliche Anwendung
Epsomite (MgSO₄·7H₂O), a naturally occurring mineral, has needle-like, orthorhombic crystals. It may be found in the saline efflorescence of the surface of some soils of arid regions. It is soluble in water, which makes magnesium easily available to plants. It is used as a source of magnesium in many chemical industries like paper, sugar refining, etc.
Epsom salt, MgSO₄·7H₂O(rhombic), is the commonest hydrate of magnesium sulphate. Used as a plant nutrient to overcome magnesium deficiency, epsom salt finds application in fertilizer manufacture besides being used in fireproofing cotton and in tanning leather. Epsom salt is also known to be a laxative.
Biochem/physiol Actions
Magnesium sulfate heptahydrate is used as a source of magnesium in foliar application of fertilizers to plants.
