  2. Iodide - Wikipedia

    en.wikipedia.org/wiki/Iodide

    The low solubility of silver iodide and lead iodide reflects the covalent character of these metal iodides. A test for the presence of iodide ions is the formation of yellow precipitates of these compounds upon treatment of a solution of silver nitrate or lead(II) nitrate. [2] Aqueous solutions of iodide salts dissolve iodine better than pure ...

    The oxidation states are also maintained in articles of the elements (of course), and systematically in the table {{Infobox element/symbol-to-oxidation-state}}

  4. Iodine compounds - Wikipedia

    en.wikipedia.org/wiki/Iodine_compounds

    Most metal iodides with the metal in low oxidation states (+1 to +3) are ionic. Nonmetals tend to form covalent molecular iodides, as do metals in high oxidation states from +3 and above. Both ionic and covalent iodides are known for metals in oxidation state +3 (e.g. scandium iodide is mostly ionic, but aluminium iodide is not).

  5. Hypervalent organoiodine compounds - Wikipedia

    en.wikipedia.org/wiki/Hypervalent_organoiodine...

    Hypervalent iodine oxyanions are known for oxidation states +1, +3, +5, and +7; organic analogues of these moieties are known for each oxidation state except +7. In terms of chemical behavior, λ 3 ‑ and λ 5 ‑iodanes are generally oxidizing and/or electrophilic species. They have been widely applied towards those ends in organic synthesis. [1]

  7. Oxidation state - Wikipedia

    en.wikipedia.org/wiki/Oxidation_state

    Oxidation states are typically represented by integers which may be positive, zero, or negative. In some cases, the average oxidation state of an element is a fraction, such as ⁠ 8 / 3 ⁠ for iron in magnetite Fe 3 O 4 . The highest known oxidation state is reported to be +9, displayed by iridium in the tetroxoiridium(IX) cation (IrO + 4). [1]

  8. Iodine oxide - Wikipedia

    en.wikipedia.org/wiki/Iodine_oxide

    • The -1 oxidation state, hydrogen iodide, is not an oxide, but it is included in this table for completeness. The periodates include two variants: metaperiodate IO − 4 and orthoperiodate IO 5− 6.

  9. Iodine - Wikipedia

    en.wikipedia.org/wiki/Iodine

    Iodine occurs in many oxidation states, including iodide (I −), iodate (IO − 3), and the various periodate anions. As the heaviest essential mineral nutrient, iodine is required for the synthesis of thyroid hormones. [7] Iodine deficiency affects about two billion people and is the leading preventable cause of intellectual disabilities. [8]
