STRONG BITTER SALINE

Aqueous solution in neutral or usually alkaline, pH 7-9

Slightly deliquescent in moist air; on long exposure to air becomes yellow due to liberation of iodine, small amount of iodate may be formed; light and moisture accelerate the decomposition; aqueous solution becomes yellow in time due to oxidation, but a small amount of alkali prevents it|30 g KI with 21 mL water gives 30 mL of a saturated solution at 25 °C|Slightly hygroscopic in moist air|Readily dissolves elemental iodine /Potassium iodide solution/

Water soluble.

Salts, Basic

Bromine trifluoride rapidly attacks potassium iodide [Mellor 2, Supp. 1:164, 165. 1956]. Potassium iodide is a weak reducing agent, and may react with strong or weak oxidizing agents.

Not flammable (USCG, 1999)
