Mercury(II) iodide is a chemical compound with the molecular formula Hg I 2. It is typically produced synthetically but can also be found in nature as the extremely rare mineral coccinite . Unlike the related mercury(II) chloride it is hardly soluble in water (<100 ppm).
Mercury(I) iodide was a commonly used as a drug in the 19th century, sometimes under the contemporary name of protiodide of mercury. It was used to treat a wide range of conditions; everything from acne to kidney disease and in particular was the treatment of choice for syphilis .
Coccinite is a rare mercury iodide mineral with chemical formula of HgI 2, mercury(II) iodide. [5] [6] It was first discovered in Casas Viejas, Mexico; [7] it has also been reported from Broken Hill, New South Wales, and from a uranium mine in Thuringia and old mercury workings in the Rhineland-Palatinate in Germany.

Mercury iodide may refer to the following chemical compounds: Mercury(I) iodide, Hg 2 I 2; Mercury(II) iodide, HgI 2 This page was last edited on 17 October ...
2 ion, found in mercury(I) (mercurous) compounds. The existence of the metal–metal bond in Hg(I) compounds was established using X-ray studies in 1927 [2] [page needed] and Raman spectroscopy in 1934 [3] making it one of the earliest, if not the first, metal–metal covalent bonds to be characterised. Other mercury polycations are the linear ...
Additives: Nearly 70% of table salt in the United States is fortified with iodide, a necessary nutrient that's been added to salt since the 1920s to help prevent iodine deficiency, according to ...
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.
