The general formula of a phosphoric acid is H n−2x+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; that is, the minimum number of bonds that would have to be broken to eliminate all cycles.
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. The phosphate or orthophosphate ion [PO 4] 3− is derived from phosphoric acid by the removal of three protons H +.
A phosphate phosphite is a chemical compound or salt that contains phosphate and phosphite anions (PO 3 3-and PO 4 3-). These are mixed anion compounds or mixed valence compounds. Some have third anions. Phosphate phosphites frequently occur as metal organic framework (MOF) compounds which are of research interest for gas storage, detection or ...
Structural formula of Na 2 HPO 3.The anion has C 3v symmetry.. From the commercial perspective, the most important phosphite salt is basic lead phosphite.Many salts containing the phosphite ion have been investigated structurally, these include sodium phosphite pentahydrate (Na 2 HPO 3 ·5H 2 O).
In biochemistry and medicinal chemistry, phosphonate groups are used as stable bioisosteres for phosphate, such as in the antiviral nucleotide analog, Tenofovir, one of the cornerstones of anti-HIV therapy. And there is an indication that phosphonate derivatives are "promising ligands for nuclear medicine." [2]
Disodium hydrogen phosphite is the name for inorganic compounds with the formula Na 2 HPO 3 •(H 2 O) x. The commonly encountered salt is the pentahydrate. [1] A derivative of phosphorous acid (HP(O)(OH) 2), it contains the anion HPO 3 2−. Its common name suggests that it contains an acidic hydrogen atom, as in sodium hydrogen carbonate ...
Phosphorous acid (or phosphonic acid) is the compound described by the formula H 3 PO 3. This acid is diprotic (readily ionizes two protons), not triprotic as might be suggested by this formula. Phosphorous acid is an intermediate in the preparation of other phosphorus compounds.
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]
