Magnesium is capable of reducing water and releasing highly flammable hydrogen gas: [137] Mg(s) + 2 H 2 O (l) → Mg(OH) 2 (s) + H 2 (g) Therefore, water cannot extinguish magnesium fires. The hydrogen gas produced intensifies the fire. Dry sand is an effective smothering agent, but only on relatively level and flat surfaces.
Alpersite (IMA symbol: Aps [1]) is a magnesium copper sulfate mineral with the chemical formula (Mg,Cu)[SO 4]·7H 2 O. It is named after United States Geological Survey geochemist Charles N. Alpers and was first described in 2006. [2]
Like magnesium oxide, it will generate a basic carbonate when placed in the air. [3] Magnesium sulfide can be produced by the reaction of magnesium and hydrogen sulfide, or by the reaction of magnesium sulfate and carbon disulfide at high temperature: [6] Mg + H 2 S → MgS + H 2 3 MgSO 4 + 4 CS 2 → 3 MgS + 4 COS + 4 SO 2
The divalent cation can be magnesium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc or cadmium. In addition to sulfate and selenate, the divalent anion can be chromate (CrO 4 2−), tetrafluoroberyllate (BeF 4 2−), hydrogenphosphate (HPO 4 2−) [2] or monofluorophosphate (PO 3 F 2−).
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 .
Copper(II) sulfate is an inorganic compound with the chemical formula Cu SO 4.It forms hydrates CuSO 4 ·nH 2 O, where n can range from 1 to 7. The pentahydrate (n = 5), a bright blue crystal, is the most commonly encountered hydrate of copper(II) sulfate, [10] while its anhydrous form is white. [11]
Noranda Inc produced Mg from its tailings ponds in Asbestos, Quebec from 2000 for about a decade [3] The magnesium smelter in Bécancour, Quebec used to be operated by Norsk Hydro, [3] and was shuttered by 2011 [2] The Dominion Magnesium Limited smelter in Haley Station, Ontario was the site for the first industrial implementation of the ...
