Lower iodides may be produced either through thermal decomposition or disproportionation, or by reducing the higher iodide with hydrogen or a metal, for example: [55] TaI 5 + Ta → 630 ∘ C ⟶ 575 ∘ C thermal gradient Ta 6 I 14 {\displaystyle {\ce {TaI5{}+Ta->[{\text{thermal gradient}}][{\ce {630

Of the thirty-seven known isotopes of iodine, only one occurs in nature, iodine-127. The others are radioactive and have half-lives too short to be primordial. As such, iodine is both monoisotopic and mononuclidic and its atomic weight is known to great precision, as it is a constant of nature.

In these solvents the absorption band maximum occurs in the 520 – 540nm region and is assigned to a π * to σ * transition. When I 2 reacts with Lewis bases in these solvents a blue shift in I 2 peak is seen and the new peak (230 – 330nm) arises that is due to the formation of adducts, which are referred to as charge-transfer complexes. [45] Hydrogen iodide [ edit ] For over 30 years Nettex have been developing and making animal health products from their base in Kent, and they are proud to still conduct all their research and manufacturing in the UK. R = Me, Et, Bu n) may still be isolated. Anhydrous hydrogen iodide is a poor solvent, able to dissolve only small molecular compounds such as nitrosyl chloride and phenol, or salts with very low lattice energies such as tetraalkylammonium halides. [47] Other binary iodine compounds [ edit ]In cases where Povidone-Iodine 10% w/w Antiseptic Tincture has been taken orally, gastric lavage with dilute starch mucilage or a 1% solution of sodium thiosulphate must be administered. The electrolyte balance must be corrected and lost fluids replaced. The other iodine radioisotopes have much shorter half-lives, no longer than days. [29] Some of them have medical applications involving the thyroid gland, where the iodine that enters the body is stored and concentrated. Iodine-123 has a half-life of thirteen hours and decays by electron capture to tellurium-123, emitting gamma radiation; it is used in nuclear medicine imaging, including single photon emission computed tomography (SPECT) and X-ray computed tomography (X-Ray CT) scans. [36] Iodine-125 has a half-life of fifty-nine days, decaying by electron capture to tellurium-125 and emitting low-energy gamma radiation; the second-longest-lived iodine radioisotope, it has uses in biological assays, nuclear medicine imaging and in radiation therapy as brachytherapy to treat a number of conditions, including prostate cancer, uveal melanomas, and brain tumours. [37] Finally, iodine-131, with a half-life of eight days, beta decays to an excited state of stable xenon-131 that then converts to the ground state by emitting gamma radiation. It is a common fission product and thus is present in high levels in radioactive fallout. It may then be absorbed through contaminated food, and will also accumulate in the thyroid. As it decays, it may cause damage to the thyroid. The primary risk from exposure to high levels of iodine-131 is the chance occurrence of radiogenic thyroid cancer in later life. Other risks include the possibility of non-cancerous growths and thyroiditis. [38]

Patients with renal impairment should refer to Section 4.4, special warnings and precautions for use. Aqueous hydrogen iodide is known as hydroiodic acid, which is a strong acid. Hydrogen iodide is exceptionally soluble in water: one litre of water will dissolve 425 litres of hydrogen iodide, and the saturated solution has only four water molecules per molecule of hydrogen iodide. [48] Commercial so-called "concentrated" hydroiodic acid usually contains 48–57% HI by mass; the solution forms an azeotrope with boiling point 126.7°C at 56.7g HI per 100g solution. Hence hydroiodic acid cannot be concentrated past this point by evaporation of water. [47] Unlike gaseous hydrogen iodide, hydroiodic acid has major industrial use in the manufacture of acetic acid by the Cativa process. [49] [50]The simplest compound of iodine is hydrogen iodide, HI. It is a colourless gas that reacts with oxygen to give water and iodine. Although it is useful in iodination reactions in the laboratory, it does not have large-scale industrial uses, unlike the other hydrogen halides. Commercially, it is usually made by reacting iodine with hydrogen sulfide or hydrazine: [46] 2 I 2 + N 2H 4 H 2O ⟶ 4 HI + N 2 Our courier will send you a 1-hour delivery window on the day of delivery and you have the option to change this if required at no extra charge or you can also let the courier know that you want the parcel left in a safe place. In patients receiving concomitant lithium therapy, regular application of Povidone-iodine 10% w/w Alcoholic Tincture should be avoided as, especially in the case of application of povidone-iodine to extensive areas, larger amounts of iodine may be absorbed. In exceptional cases, this can induce (transient) hypothyroidism. In this special situation, a synergistic effect might also occur as lithium may also induce hypothyroidism.
