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. [5]
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 .
Potassium-magnesium sulfate double salt, a good fertilizer, is a salt that precipitates from bitterns upon addition of methanol. [3] Ethanol is also used, but it exhibits a preference for potassium sulfate precipitation. [3] The solution can furthermore be used in the production of potash and potassium salts. [10]
Fertilizers are usually labeled with three numbers, as in 18-20-10, indicating the relative content of the primary macronutrients nitrogen (N), phosphorus (P), and potassium (K), respectively. More precisely, the first number ("N value") is the percentage of elemental nitrogen by weight in the fertilizer; that is, the mass fraction of nitrogen ...
A crucible and tongs, on a green mat. The ash content of a sample is a measure of the amount of inorganic noncombustible material it contains. The residues after a sample is completely burnt - in contrast to the ash remaining after incomplete combustion - typically consist of oxides of the inorganic elements present in the original sample.
Magnesium reacted with an alkyl halide gives a Grignard reagent, which is a very useful tool for preparing alcohols. Magnesium salts are included in various foods, fertilizers (magnesium is a component of chlorophyll), and microbe culture media. Magnesium sulfite is used in the manufacture of paper (sulfite process).
The United States on Thursday banned imports from five more Chinese companies over alleged human rights abuses involving the Uyghurs, according to a government posting, as part of its effort to ...
The Caprolactam plant in Udyogamandal was commissioned in 1990. Main products include ammonia, sulfuric acid, ammonium phosphate-sulfate (FACTAMFOS), ammonium sulfate, zincated ammonium phosphate, caprolactam, and also complex fertilizers. gypsum, nitric acid, soda ash and coloured ammonium sulfate are major by-products.
