| Air and Water Reactions: | Soluble in water with small release of heat. | Reactive Group: | Acids, Weak |
| Reactivity Profile: | PHOSPHORIC ACID reacts exothermically with bases. May react with active metals, including such structural metals as aluminum and iron, to release hydrogen, a flammable gas. Can initiate the polymerization of certain classes of organic compounds. Reacts with cyanide compounds to release gaseous hydrogen cyanide. May generate flammable and/or toxic gases in contact with dithiocarbamates, isocyanates, mercaptans, nitrides, nitriles, sulfides, and strong reducing agents. Forms explosive mixture with nitromethane. Reacts violently with sodium tetrahydroborate. In the presence of chlorides can corrode stainless steel to form explosive hydrogen gas. Emits toxic and irritating fumes of oxides of phosphorus when heated to decomposition [Lewis, 3rd ed., 1993, p. 1029]. | Autoignition Temperature: | Not flammable (USCG, 1999) |
| Flammable Limits: | Noncombustible Solid | Corrosivity: | Corrosive to ferrous metals and alloys |
