The term phosphate is also used in organic chemistry for the functional groups that result when one or more of the hydrogens are replaced by bonds to other groups. These acids, together with their salts and esters , include some of the best-known compounds of phosphorus, of high importance in biochemistry , mineralogy , agriculture , pharmacy ...
Phosphate rock production greatly increased after World War II, and remains the primary global source of phosphorus and phosphorus chemicals today. Phosphate rock remains a feedstock in the fertiliser industry, where it is treated with sulfuric acid to produce various "superphosphate" fertiliser products.
In biological systems, phosphorus can be found as free phosphate anions in solution (inorganic phosphate) or bound to organic molecules as various organophosphates. Inorganic phosphate is generally denoted P i and at physiological ( homeostatic ) pH primarily consists of a mixture of [HPO
[2] [3] "Phosphoryl" groups are covalently bonded by a single bond to an organic molecule, phosphate group(s) or another "phosphoryl" group(s), and those groups are sp 3 hybridized at the phosphorus atom. [4] The term "phosphoryl" in the mentioned branches is usually used in the description of catalytic mechanisms in living organisms.
A sodium phosphate is a generic variety of salts of sodium (Na +) and phosphate (PO 3− 4). Phosphate also forms families or condensed anions including di-, tri-, tetra-, and polyphosphates . Most of these salts are known in both anhydrous (water-free) and hydrated forms.
Phosphate is an inorganic anion of phosphoric acid OP(OH) 3. ... Phosphorus oxoacid; Phosphotungstic acid; Polyphosphate; Potassium dideuterium phosphate;
Produced from phosphate embedded in rocks, white phosphorus is a toxic substance that’s used in fertilizers, cleaning compounds as well as military tools and weapons, according to the Centers ...
Elemental phosphorus is distilled out of the furnace and burned with air to produce high-purity phosphorus pentoxide, which is dissolved in water to make phosphoric acid. [22] The thermal process produces phosphoric acid with a very high concentration of P 2 O 5 (about 85%) and a low level of impurities.
