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 .
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
The table below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/ (100 mL)), unless shown otherwise. The substances are listed in alphabetical order.
Contents. Lewis acids and bases. A Lewis acid (named for the American physical chemist Gilbert N. Lewis) is a chemical species that contains an empty orbital which is capable of accepting an electron pair from a Lewis base to form a Lewis adduct. A Lewis base, then, is any species that has a filled orbital containing an electron pair which is ...
If magnesium chloride (or sulfate) is treated with aqueous sodium carbonate, a precipitate of basic magnesium carbonate – a hydrated complex of magnesium carbonate and magnesium hydroxide – rather than magnesium carbonate itself is formed: 5 MgCl 2 (aq) + 5 Na 2 CO 3 (aq) + 5 H 2 O(l) → Mg 4 (CO 3) 3 (OH) 2 ·3H 2 O(s) + Mg(HCO 3) 2 (aq ...
Cobalt (II) sulfate is any of the inorganic compounds with the formula CoSO 4 (H 2 O) x. Usually cobalt sulfate refers to the hexa- or heptahydrates CoSO 4. 6H 2 O or CoSO 4. 7H 2 O, respectively. [1] The heptahydrate is a red solid that is soluble in water and methanol. Since cobalt (II) has an odd number of electrons, its salts are paramagnetic.
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 ...
Magnesium compounds. Magnesium compounds are compounds formed by the element magnesium (Mg). These compounds are important to industry and biology, including magnesium carbonate, magnesium chloride, magnesium citrate, magnesium hydroxide (milk of magnesia), magnesium oxide, magnesium sulfate, and magnesium sulfate heptahydrate (Epsom salts).
