Potassium Iodide | KI or IK | CID 4875 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more.
Potassium iodide has the chemical formula K I. [8] Commercially it is made by mixing potassium hydroxide with iodine. [9][10] Potassium iodide has been used medically since at least 1820. [11] It is on the World Health Organization's List of Essential Medicines. [12]
Potassium iodide (KI) is prepared by reacting potassium hydroxide to iodine with a hot solution. It is used mainly in the form of a saturated solution, 100 g potassium iodide to 100 ml water. That equates to around 50 mg/drop.
The boiling point of KI is 1,330 °C (2,426 °F). This high boiling point is due to the strong ionic bonding between potassium and iodine atoms in the compound. KI is used in high-temperature applications due to its ability to withstand extreme heat without decomposing or losing its effectiveness.

The dose is 0.5 g-1.0 g in 100 mL, with the accompany of iodine (0.5 g-1.0 g in 100 mL). KI is also used as a fluorescence quenching agent in biomedical research because of collisional quenching by its iodide ion.
