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 ...
Nevertheless, the iodide in tincture of iodine used as a water disinfectant does supply more than adequate nutritional iodine, perhaps 30 or more times the recommended daily allowance per liter or quart. Application of tincture or Lugol's to the skin also results in absorption and bioavailability of some moderate fraction of the iodine.
Through this reaction, iodine is used in redox titrations. Aqueous KI 3 (Lugol's iodine) solution is used as a disinfectant and as an etchant for gold surfaces. Potassium iodide and silver nitrate are used to make silver(I) iodide, which is used for high speed photographic film and for cloud seeding: KI (aq) + 9 AgNO 3 (aq) → AgI (s) + KNO 3 (aq)

The dyes used for chromoendoscopy are typically considered to be safe. Some dyes such as indigo carmine may discolour the feces temporarily. Lugol's iodine when applied to the esophagus can lead to discomfort, inflammation (of the esophagus or stomach) or rarely allergy. Sodium thiosulfate has been used to avert this. [1]
It appears from reading the article that Lugol's Iodine is an aqueous solution of a 2:1 mixture of KI and I 2 by weight. This would correspond to a 3:1 molar ratio (which makes sense as I − needs to be in excess). Perhaps this could be written as "Lugol's Iodine is a solution of KI/I 2 (3:1) in water." IMO the details of the various ...
