  2. Mercury(II) iodide - Wikipedia

    en.wikipedia.org/wiki/Mercury(II)_iodide

    Mercury(II) iodide crystals grown in Spacelab. Mercury(II) iodide is used for preparation of Nessler's reagent, used for detection of presence of ammonia.. Mercury(II) iodide is a semiconductor material, used in some x-ray and gamma ray detection and imaging devices operating at room temperatures.

  3. Solubility chart - Wikipedia

    en.wikipedia.org/wiki/Solubility_chart

    The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

    en.wikipedia.org/wiki/Mercury(I)_iodide

    In common with other Hg(I) (mercurous) compounds which contain linear X-Hg-Hg-X units, Hg 2 I 2 contains linear IHg 2 I units with an Hg-Hg bond length of 272 pm (Hg-Hg in the metal is 300 pm) and an Hg-I bond length of 268 pm. [2] The overall coordination of each Hg atom is octahedral as it has in addition to the two nearest neighbours there are four other I atoms at 351 pm. [2] The compound ...

    , which forms an insoluble Hg(II) salt, induces complete disproportionation, whereas Cl − , which forms an insoluble Hg(I) salt, induces the reverse. [ 3 ] Most salts with main group elements tend to contain only Hg(II) and metallic mercury, because the presence of strong Lewis bases destabilizes the intermetallic bond.

  8. Mercury(I) oxide - Wikipedia

    en.wikipedia.org/wiki/Mercury(I)_oxide

    It is a brown/black powder, insoluble in water but soluble in nitric acid. With hydrochloric acid, it reacts to form calomel, Hg 2 Cl 2. [4] Mercury(I) oxide is toxic but without taste or smell. It is chemically unstable and converts to mercury(II) oxide and mercury metal.
