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 ...
Potassium iodide: KI white crystals iodine component of iodized salt Hydrogen iodide: HI colourless gas strong mineral acid Silver iodide: AgI yellow powder that darkens in light photoactive component of silver-based photographic film Thyroxine (3,5,3′,5′-tetraiodothyronine) C 15 H 11 I 4 NO 4: pale yellow solid hormone essential for human ...
Melzer's reagent is an aqueous solution of chloral hydrate, potassium iodide, and iodine.Depending on the formulation, it consists of approximately 2.50-3.75% potassium iodide and 0.75–1.25% iodine, with the remainder of the solution being 50% water and 50% chloral hydrate.
Iodine-131 (usually as iodide) is a component of nuclear fallout, and is particularly dangerous owing to the thyroid gland's propensity to concentrate ingested iodine and retain it for periods longer than this isotope's radiological half-life of eight days. For this reason, people at risk of exposure to environmental radioactive iodine (iodine ...
Aug. 11—WILKES-BARRE — The Pennsylvania Department of Health (DOH) will offer free potassium iodide, or KI, tablets on Aug. 22 to Pennsylvanians who live or work within 10 miles of the state's ...
Ground Based Silver Iodide Generator – Colorado, US . The most common chemicals used for cloud seeding include silver iodide, [4] potassium iodide and dry ice (solid carbon dioxide). Liquid propane, which expands into a gas, has also been used. It can produce ice crystals at higher temperatures than silver iodide.
Since bismuth(III) iodide is insoluble in water, an aqueous solution can be tested for the presence of Bi 3+ ions by adding a source of iodide such as potassium iodide. A black precipitate of bismuth(III) iodide indicates a positive test. [10] Bismuth(III) iodide forms iodobismuth(III) anions when heated with halide donors: [11] 2 NaI + BiI 3 ...
Iodized salt, containing potassium iodide, is widely available. Some people put a desiccant , such as a few grains of uncooked rice [ 38 ] or a saltine cracker , in their salt shakers to absorb extra moisture and help break up salt clumps that may otherwise form.
