Potassium nitrite is a granular,
crystalline material with an off-white-to-straw color. It is
hygroscopic, deliquescent and very soluble in water. It decomposes
in acid solutions to form unstable nitrous acid. Potassium nitrite
is sold as a moist crystal to help delay the onset of caking. Some
downward migration of moisture can occur in drums during storage.
