chemical properties white to yellow crystals
general description a yellowish white crystalline solid. noncombustible but accelerates the burning of all combustible material. if large quantities are involved in fire or if the combustible material is finely divided, an explosion may result. may explode under prolonged exposure to heat. toxic oxides of nitrogen are produced in fires. used to make other chemicals and in chemical analysis.
air & water reactions water soluble.
reactivity profile potassium nitrite is an oxidizing agent. mixtures with phosphorus, tin(ii) chloride or other reducing agents may react explosively [bretherick 1979 p. 108-109]. contamination by ammonium compounds can initiate spontaneous decomposition. the resulting heat may ignite surrounding combustible material. reacts with acids to form toxic nitrogen dioxide gas. mixing with liquid ammonia forms dipotassium nitrite, which is very reactive and easily explosive [mellor 2, supp. 3:1566 1963]. melting together with an ammonium salt leads to a violent explosion [von schwartz 1918 p. 299]. a mixture with potassium cyanide may cause an explosion. when a little ammonium sulfate is added to fused potassium nitrite, a vigorous reaction occurs attended by flame [mellor 2:702. 1946-47].
health hazard inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death. fire may produce irritating, corrosive and/or toxic gases. runoff from fire control or dilution water may cause pollution.
fire hazard these substances will accelerate burning when involved in a fire. some may decompose explosively when heated or involved in a fire. may explode from heat or contamination. some will react explosively with hydrocarbons (fuels). may ignite combustibles (wood, paper, oil, clothing, etc.). containers may explode when heated. runoff may create fire or explosion hazard.
