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 .
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).
Compared to the elemental form, potassium iodide has a median lethal dose (LD 50) that is relatively high in several animals: in rabbits, it is 10 g/kg; in rats, 14 g/kg, and in mice, 22 g/kg. [73] The tolerable upper intake level for iodine as established by the Food and Nutrition Board is 1,100 μg/day for adults. The safe upper limit of ...
For example, in the molecules represented by CH 3 X, where X is a halide, the carbon-X bonds have strengths, or bond dissociation energies, of 115, 83.7, 72.1, and 57.6 kcal/mol for X = fluoride, chloride, bromide, and iodide, respectively. [2] Of the halides, iodide usually is the best leaving group.
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 ...
Lugol's iodine is a liquid made up of two parts potassium iodide for every one part elemental iodine in water. [8] Lugol's iodine was first made in 1829 by the French physician Jean Lugol. [7] [8] It is on the World Health Organization's List of Essential Medicines. [9] [10] Lugol's iodine is available as a generic medication and over the ...
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.

The sodium/iodide cotransporter, also known as the sodium/iodide symporter (NIS), [5] is a protein that in humans is encoded by the SLC5A5 gene. [6] [7] [8] It is a transmembrane glycoprotein with a molecular weight of 87 kDa and 13 transmembrane domains, which transports two sodium cations (Na +) for each iodide anion (I −) into the cell. [9]
