          Soluble in ammonia and water, aqueous solution was alkaline. Slightly soluble in alcohol, not the solution in acetone. At 350. C decomposition begin to generate potassium and release nitric oxide gas. Asia potassium nitrate as oxidant, toxic! With organic matter. Contact with combustible mixture to combustion and explosion, and release toxic and irritating the peroxy nitrogen and nitric oxide gas. Mixed with iron salts or cyanide explode.
