Phosphoric acid (orthophosphoric acid, monophosphoric acid or phosphoric(V) acid) is a colorless, odorless phosphorus-containing solid, and inorganic compound with the chemical formula H 3 P O 4. It is commonly encountered as an 85% aqueous solution, which is a colourless, odourless, and non-volatile syrupy liquid. It is a major industrial ...
Pyrophosphoric acid. In chemistry, a phosphoric acid, in the general sense, is a phosphorus oxoacid in which each phosphorus (P) atom is in the oxidation state +5, and is bonded to four oxygen (O) atoms, one of them through a double bond, arranged as the corners of a tetrahedron.
In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid.It most commonly means orthophosphate, a derivative of orthophosphoric acid, a.k.a. phosphoric acid H 3 PO 4.
Hypophosphoric acid can be prepared by the reaction of red phosphorus with sodium chlorite at room temperature. [2]2 P + 2 NaClO 2 + 2 H 2 O → Na 2 H 2 P 2 O 6 + 2 HCl. A mixture of hypophosphoric acid, phosphorous acid (H 3 PO 3) and phosphoric acid (H 3 PO 4) is produced when white phosphorus oxidises in air when partially immersed in water.

DEA List I chemical status [ edit ] Because hypophosphorous acid can reduce elemental iodine to form hydroiodic acid , which is a reagent effective for reducing ephedrine or pseudoephedrine to methamphetamine , [ 11 ] the United States Drug Enforcement Administration designated hypophosphorous acid (and its salts) as a List I precursor chemical ...
The IUPAC (mostly organic) name is phosphonic acid. This nomenclature is commonly reserved for substituted derivatives, that is, organic group bonded to phosphorus, not simply an ester. For example, (CH 3)PO(OH) 2 is "methylphosphonic acid", which may of course form "methylphosphonate" esters.
Hydrogen phosphate or monohydrogen phosphate (systematic name) is the inorganic ion with the formula [HPO 4] 2-. Its formula can also be written as [PO 3 (OH)] 2-. Together with dihydrogen phosphate, hydrogenphosphate occurs widely in natural systems. Their salts are used in fertilizers and in cooking. [1]
