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 renders the elementary iodine soluble in water through the formation of the triiodide (I − 3) ion. It is not to be confused with tincture of iodine solutions, which consist of elemental iodine, and iodide salts dissolved in water and alcohol. Lugol's solution contains no alcohol.

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 ...
The salt consists of the ethylenediammonium dication C 2 H 4 (NH 3) 2 2+ and iodide anions. Application ... (most stable) and potassium iodide. See also
Approved by the World Health Organization for radiation protection, potassium iodate (KIO 3) is an alternative to potassium iodide (KI), which has poor shelf life in hot and humid climates. [10] The UK, Singapore, United Arab Emirates, and the U.S. states Idaho and Utah all maintain potassium iodate tablets towards this end.
