1. Potassium Iodide, also called KI is a salt of stable (not radioactive) iodine. The compound is required by the body to make thyroid hormones.
2. The major uses of potassium iodide include nutritional supplement in animal feeds. It is also used medicinally in tablets, and also fins application in hair dyes.
3. Potassium Iodide is sometimes added in small quantities to table salt for idolization. This crystalline salt is also used as a fluorescence quenching agent in biomedical research because of collisional quenching by its iodide ion.
