Potassium iodide is a component in the electrolyte of dye sensitised solar cells (DSSC) along with iodine. Potassium iodide finds its most important applications in organic synthesis mainly in the preparation of aryl iodides in the Sandmeyer reaction, starting from aryl amines. Aryl iodides are in turn used to attach aryl groups to other ...
The term immediately dangerous to life or health (IDLH) is defined by the US National Institute for Occupational Safety and Health (NIOSH) as exposure to airborne contaminants that is "likely to cause death or immediate or delayed permanent adverse health effects or prevent escape from such an environment." Examples include smoke or other ...
Side effects may include allergic reactions, headache, vomiting, and conjunctivitis. [4] [1] Long term use may result in trouble sleeping and depression. [4] It should not typically be used during pregnancy or breastfeeding. [4] Lugol's iodine is a liquid made up of two parts potassium iodide for every one part elemental iodine in water. [8]
The black precipitate of bismuth iodide is formed from the reaction of bismuth ion and potassium iodide. Bi 3+ + 3 KI → BiI 3 + 3 K + Then, the reaction between bismuth ion and excess potassium iodide will produce a soluble complex of potassium tetraiodobismuthate which has an orange color. BiI 3 + KI → K(BiI 4)
R-phrases (short for risk phrases) are defined in Annex III of European Union Directive 67/548/EEC: Nature of special risks attributed to dangerous substances and preparations. The list was consolidated and republished in Directive 2001/59/EC, [ 1 ] where translations into other EU languages may be found.
In some ways the Jod-Basedow phenomenon is the opposite of two physiological compensation mechanisms, the Plummer effect and the Wolff–Chaikoff effect, which in normal persons and in persons with thyroid disease, suppress the thyroid hormone after ingestion of large quantities of iodine or iodide. However, unlike the Plummer and Wolff ...
“I have guns, gold, potassium iodide, antibiotics, batteries, water, gas masks from the Israeli Defense Force, and a big patch of land in Big Sur I can fly to,” he said.
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 ...
