Description
A hygroscopic, brown solid used as an etchant in photoengraving as a Mordant to produce a clean vertical edge. Ferric chloride is also used as a mordant in textile dyeing and as a brown pigment in paints and inks. An acidified solution of iron chloride is also used as a reagent to qualitatively test for the presence of Arsenic or Phosphorus in Copper alloys (Odegaard et al 2000).
Synonyms and Related Terms
iron (III) chloride; ferric trichloride; ferric perchloride; iron chloride; iron trichloride; iron perchloride; Flores Martin; Eisen(III)chlorid (Deut.); chlorure de fer (III) (Fr.);
Risks
- Noncombustible.
- Toxic by ingestion and inhalation.
- The corrosive, acidic compound will causes burns on contact.
- Decomposes in heat to form hydrogen chloride gas.
- Fisher Scientific: SDS
Physical and Chemical Properties
Soluble in water, ethanol, ether, acetone. Insoluble in ethyl acetate. Solid is deliquescent forming hexahydrate compound. Dissolution in water is exothermic and produced an acidic solution.
