2 Na 2 HPO 4 + NaH 2 PO 4 → Na 5 P 3 O 10 + 2 H 2 O. Phosphorus pentoxide (P 4 O 10) is the acid anhydride of phosphoric acid, but several intermediates between the two are known. This waxy white solid reacts vigorously with water. With metal cations, phosphate forms a variety of salts. These solids are polymeric, featuring P-O-M linkages.
Contrary to biology, biochemistry and biomedicine branches, in organic and inorganic chemistry branches, and in the branch of chemical nomenclature (see IUPAC), the correct name for the −P(=O)(−O −) 2 group is not "phosphoryl", but phosphonato, and the correct name for the −P(=O)(−OH) 2 group is phosphono, and the term phosphoryl ...
The general formula of a phosphoric acid is H n+2−2x P n O 3n+1−x, where n is the number of phosphorus atoms and x is the number of fundamental cycles in the molecule's structure, between 0 and n + 2 / 2 . Pyrophosphate anion. Trimethyl orthophosphate.
Phosphorus comprises 0.1% by mass of the average rock [12] (while, for perspective, its typical concentration in vegetation is 0.03% to 0.2%), [13] and consequently there are quadrillions of tons of phosphorus in Earth's 3×10 19-ton crust, [14] albeit at predominantly lower concentration than the deposits counted as reserves, which are ...
Organophosphorus chemistry is the scientific study of the synthesis and properties of organophosphorus compounds, which are organic compounds containing phosphorus. [1] They are used primarily in pest control as an alternative to chlorinated hydrocarbons that persist in the environment.
White phosphorus, yellow phosphorus or simply tetraphosphorus (P 4) exists as molecules of four phosphorus atoms in a tetrahedral structure, joined by six phosphorus—phosphorus single bonds. [1] The free P 4 molecule in the gas phase has a P-P bond length of r g = 2.1994(3) Å as was determined by gas electron diffraction . [ 2 ]
Their generic formula is H n−x+2 P n O 3n−x+1, where n is the number of phosphorus atoms and x is the number of fundamental cycles in the molecule's structure. These acids, and their esters and salts ("phosphates") include some of the best-known and most important compounds of phosphorus. Orthophosphoric acid, H 3 PO 4. The simplest member ...
The insecticide fosthietan is a phosphoramidate. In organophosphorus chemistry, phosphoramidates (sometimes also called amidophosphates) are a class of phosphorus compounds structurally related to phosphates (or organophosphates) via the substitution of an −O − group for an amine group (−N−).
