Brown form: reddish-brown granules, garnet-red transparent scales, or brownish-yellow powder. Very deliquescent. Odorless or slight ammonia odor; saline, ferruginous taste. Ammonium ferric citrate, brown form reduced to ferrous salt by light. Brown hydrated form is extremely soluble in water and practically insoluble in alcohol. /Hydrated ferric ammonium citrate/|Green form: green transparent, scales, pearls, granules, or powder. Odorless. Mild ferruginous taste. Ammonium ferric citrate, green form is more readily reduced to the ferrous salt by light then the brown form. Green hydrated form is very soluble in water and practically insoluble in alcohol. /Hydrated ferric ammonium citrate/|Deliquescent

Water soluble.

Salts, Acidic

Acidic salts, such as FERRIC AMMONIUM CITRATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions. Special Hazards of Combustion Products: Toxic oxides of nitrogen or ammonia gas may be formed in fires (USCG, 1999).
