General

Potassium iodide is an inorganic compound with the chemical formula KI. This white salt is the most commercially significant iodide compound. It is less hygroscopic (absorbs water less readily) than sodium iodide, making it easier to work with. Aged and impure samples are yellow because of aerial oxidation of the iodide to elemental iodine.
