| Chemical Properties | Colorless, viscous liquid. Miscible with water. |
| Uses | Metal cleaners, electrolytic or chemical polishing agents, formation of protective coatings for
metal surfaces, catalyst. |
| Definition | ChEBI: Fluorophosphoric acid is a fluorine molecular entity and a phosphoric acid derivative. |
| General Description | A colorless liquid. Corrosive to metals and tissue. Used in metal cleaning, as a chemical polishing agent and as a catalyst. |
| Air & Water Reactions | Soluble in water with release of heat. |
| Reactivity Profile | FLUOROPHOSPHORIC ACID neutralizes chemical bases (for example: amines and metal hydroxides) to form salts. Neutralization can generate dangerously large amounts of heat in small spaces. 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. Incompatible with sodium tetrahydroborate. May react with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), and carbonates. May catalyze (increase the rate) of chemical reactions. |
| Hazard | Strong irritant to tissue. |
| Health Hazard | TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. |
| Fire Hazard | Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. |
| Safety Profile | A corrosive and irritating material to skin, eyes, and mucous membranes. When heated to decomposition it emits very toxic fumes of Fand POx. See also FLUORIDES. |
