  2. Oxyanion - Wikipedia

    en.wikipedia.org/wiki/Oxyanion

    By contrast, the univalent anions perchlorate and permanganate ions are very difficult to protonate and so the corresponding acids are strong acids. Although acids such as phosphoric acid are written as H 3 PO 4, the protons are attached to oxygen atoms forming hydroxyl groups, so the formula can also be written as OP(OH) 3 to better reflect ...

    en.wikipedia.org/.../Phosphoric_acids_and_phosphates

    The single-bonded oxygen atoms that are not shared are completed with acidic hydrogen atoms. The general formula of a phosphoric acid is H n+2−2x P n O 3n+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 ...

  5. Phosphate - Wikipedia

    en.wikipedia.org/wiki/Phosphate

    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 +.

  6. 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. Some of them are unstable and have not been isolated, but the derived anions and organic groups are present in stable salts and ...

    The formal list is used. The name of the most electronegative element is modified to end in -ide and the more electropositive elements name is left unchanged. Taking the binary compound of sodium and chlorine: chlorine is found first in the list so therefore comes last in the name. Other examples are PCl 5 phosphorus pentachloride

    The cation is always named first. Ions can be metals, non-metals or polyatomic ions. Therefore, the name of the metal or positive polyatomic ion is followed by the name of the non-metal or negative polyatomic ion. The positive ion retains its element name whereas for a single non-metal anion the ending is changed to -ide.

    The model is defined in terms of a list of those complex species which are present in solutions in significant amounts. In the present context the complex species have the general formula [M p O q (OH) r] n±. where p, q and r define the stoichiometry of the species and n± gives the electrical charge of the ion. The experimental data are ...
