  2. Oxyacid - Wikipedia

    en.wikipedia.org/wiki/Oxyacid

    An oxyacid, oxoacid, or ternary acid is an acid that contains oxygen. Specifically, it is a compound that contains hydrogen, oxygen, and at least one other element , with at least one hydrogen atom bonded to oxygen that can dissociate to produce the H + cation and the anion of the acid.

  3. Phosphorus oxoacid - Wikipedia

    en.wikipedia.org/wiki/Phosphorus_oxoacid

    In chemistry, phosphorus oxoacid (or phosphorus acid) is a generic name for any acid whose molecule consists of atoms of phosphorus, oxygen, and hydrogen. [1] There is a potentially infinite number of such compounds.

  4. Phosphoric acids and phosphates - Wikipedia

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

    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 .

  5. Keto acid - Wikipedia

    en.wikipedia.org/wiki/Keto_acid

    In organic chemistry, keto acids or ketoacids (also called oxo acids or oxoacids) are organic compounds that contain a carboxylic acid group (−COOH) and a ketone group (>C=O). [1] In several cases, the keto group is hydrated. The alpha-keto acids are especially important in biology as they are involved in the Krebs citric acid cycle and in ...

  6. Sulfur oxoacid - Wikipedia

    en.wikipedia.org/wiki/Sulfur_oxoacid

    Sulfur oxoacids are chemical compounds that contain sulfur, oxygen, and hydrogen.The best known and most important industrially used is sulfuric acid.Sulfur has several oxoacids; however, some of these are known only from their salts (these are shown in italics in the table below).

  7. Oxyanion - Wikipedia

    en.wikipedia.org/wiki/Oxyanion

    Sulfuric acid may be written as O 2 S(OH) 2; this is the molecule observed in the gas phase. The phosphite ion, PO 3− 3 , is a strong base , and so always carries at least one proton. In this case the proton is attached directly to the phosphorus atom with the structure HPO 2− 3 .

  9. Hypofluorous acid - Wikipedia

    en.wikipedia.org/wiki/Hypofluorous_acid

    Hypofluorous acid, chemical formula H O F, is the only known oxyacid of fluorine and the only known oxoacid in which the main atom gains electrons from oxygen to create a negative oxidation state. The oxidation state of the oxygen in this acid (and in the hypofluorite ion OF − and in its salts called hypofluorites) is 0, while its valence is 2.
