  2. Phosphate - Wikipedia

    en.wikipedia.org/wiki/Phosphate

    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) −

  3. Phosphorus - Wikipedia

    en.wikipedia.org/wiki/Phosphorus

    Phosphorus is classified as a pnictogen, together with nitrogen, arsenic, antimony, bismuth, and moscovium. Phosphorus is an element essential to sustaining life largely through phosphates, compounds containing the phosphate ion, PO 4 3−. Phosphates are a component of DNA, RNA, ATP, and phospholipids, complex compounds fundamental to cells.

  4. Phosphorous acid - Wikipedia

    en.wikipedia.org/wiki/Phosphorous_acid

    Phosphorous acid (or phosphonic acid) is the compound described by the formula H3PO3. 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. Organic derivatives of phosphorous acid, compounds with the formula ...

  5. Phosphoric acids and phosphates - Wikipedia

    en.wikipedia.org/wiki/Phosphoric_acids_and...

    The single-bonded oxygen atoms that are not shared are completed with acidic hydrogen atoms. The general formula of a phosphoric acid is Hn+2−2xPnO3n+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.

  6. Phosphite anion - Wikipedia

    en.wikipedia.org/wiki/Phosphite_anion

    A phosphite anion or phosphite in inorganic chemistry usually refers to [HPO 3] 2− but includes [H 2 PO 3] − ( [HPO 2 (OH)] −). These anions are the conjugate bases of phosphorous acid (H 3 PO 3). The corresponding salts, e.g. sodium phosphite (Na 2 HPO 3) are reducing in character.

  7. Phosphorus cycle - Wikipedia

    en.wikipedia.org/wiki/Phosphorus_cycle

    The phosphorus cycle is the biogeochemical cycle that involves the movement of phosphorus through the lithosphere, hydrosphere, and biosphere.Unlike many other biogeochemical cycles, the atmosphere does not play a significant role in the movement of phosphorus, because phosphorus and phosphorus-based materials do not enter the gaseous phase readily, [1] as the main source of gaseous phosphorus ...

  8. Phosphide - Wikipedia

    en.wikipedia.org/wiki/Phosphide

    In chemistry, a phosphide is a compound containing the P3− ion or its equivalent. Many different phosphides are known, with widely differing structures. [1] Most commonly encountered on the binary phosphides, i.e. those materials consisting only of phosphorus and a less electronegative element. Numerous are polyphosphides, which are solids ...

  9. Dihydrogen phosphate - Wikipedia

    en.wikipedia.org/wiki/Dihydrogen_phosphate

    Dihydrogen phosphate is an inorganic ion with the formula [H 2 PO 4] −.Phosphates occur widely in natural systems. [1]These sodium phosphates are artificially used in food processing and packaging as emulsifying agents, neutralizing agents, surface-activating agents, and leavening agents providing humans with benefits.
