CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Ferric chloride is an orange to brown-black solid. It is slightly soluble in water. It is noncombustible. When wet it is corrosive to aluminum and most metals. Pick up and remove spilled solid before adding water. It is used to treat sewage, industrial waste, to purify water, as an etching agent for engraving circuit boards, and in the manufacture of other chemicals. |
|---|---|
| Color/Form | Hexagonal red by transmitted light, green by reflected light; sometimes appears brownish-black; dark leaflets or plates. |
| Boiling Point | 599 °F at 760 mmHg (Decomposes) (NTP, 1992) |
| Melting Point | 583 °F (NTP, 1992) |
| Solubility | 5 to 10 mg/mL at 68 °F (NTP, 1992) |
| Density | 2.8 at 68 °F (anhydrous solid) (USCG, 1999) - Denser than water; will sink |
| Vapor Pressure | 1 mmHg at 381 °F (NTP, 1992) |
| Decomposition | When heated to decomposition it emits highly toxic fumes of /hydrogen chloride/. |
| Corrosivity | Water solutions are acidic and corrosive to most metals. |
| Other Experimental Properties | Dimeric at about 400 °C but monomeric above 750 °C; dissociates at high temperature to ferrous chloride and chlorine. Very hygroscopic. |
| Chemical Classes | Metals -> Metals, Inorganic Compounds |
