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 .
Epsomite crystallizes in the orthorhombic system. The normal form is as massive encrustations, while acicular or fibrous crystals are rarely found. It is colorless to white with tints of yellow, green and pink. It is a soft mineral with variable Mohs hardness around 2.0~2.5, and it has a low specific gravity of 1.67.[5]
Magnesium sulfate as a medication is used to treat and prevent low blood magnesium and seizures in women with eclampsia. [1] It is also used in the treatment of torsades de pointes, severe asthma exacerbations, constipation, and barium poisoning. [1][2] It is given by injection into a vein or muscle as well as by mouth. [1][2] As epsom salts ...
Kieserite, or magnesium sulfate monohydrate, is a hydrous magnesium sulfate mineral with formula (MgSO 4 ·H 2 O). It has a vitreous luster and it is colorless, grayish-white or yellowish. Its hardness is 3.5 and crystallizes in the monoclinic crystal system. Gunningite is the zinc member of the kieserite group of minerals.
The now empty angular holes are interpreted as being cavities once filled by a highly soluble mineral species, most likely a magnesium sulfate. These cavities are observed to closely match the crystal habit of meridianiite, and have been proposed as sites where crystals of meridianiite were located, having subsequently dissolved when ...
Crystals of hydrated copper(II) sulfate consist of [Cu(H 2 O) 4] 2+ centers linked to SO 2− 4 ions. Copper is surrounded by six oxygen atoms, provided by two different sulfate groups and four molecules of water. A fifth water resides elsewhere in the framework but does not bind directly to copper.
