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]
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 ...
The phosphate ion has a molar mass of 94.97 g/mol, and consists of a central phosphorus atom surrounded by four oxygen atoms in a tetrahedral arrangement. It is the conjugate base of the hydrogen phosphate ion H(PO 4) 2−, which in turn is the conjugate base of the dihydrogen phosphate ion H 2 (PO 4) −
Hydrogen phosphate may refer to Monohydrogen phosphate, inorganic ion with the formula [HPO 4] 2−; Dihydrogen phosphate, inorganic ion with the formula [H 2 PO 4] ...
Removal of all three H + ions gives the phosphate ion PO 3− 4. Removal of one or two protons gives dihydrogen phosphate ion H 2 PO − 4, and the hydrogen phosphate ion HPO 2− 4, respectively. Phosphoric acid forms esters, called organophosphates. [17]
One of the two phosphate ions which can be singular to 1 metal ion Monohydrogen phosphate, commonly known as hydrogenphosphate, also known as biphosphate(2-) ([HPO 4] 2-). Dihydrogen phosphate, also known as biphosphate(1-) ([H 2 PO 4] −). Any salt of phosphoric acid in which only one of the hydrogen atoms has been replaced by a metal ion ...
Sodium dihydrogen phosphate Sodium hydrogen phosphate Trisodium phosphate. 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 ...
