Description
Ferric ammonium citrate is a yellowish brown to red solid with a faint odor of ammonia. It is soluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. It is used in medicine, in making blueprints, and as a feed additive.

Other Experimental
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;Very stable to air oxidation. If water is removed by vacuum desiccation, the dehydrated ferrous salt rapidly oxidizes to a ferric salt. ...Very slightly colored powder or white crystals /Decahydrate/;White microscopic rhombic, orthorhombic crystals; mp: decomposition at 350 °C in molecular hydrogen; soluble in ammonium hydroxide. /Monohydrate/;Reddish-brown scales /Decahydrate/;Powder. Practically insoluble in water, alcohol, acetone. /Monohydrate/;Sugar, glycerin, & many organic hydroxy acids hinder precipitation. In neutral solution, soluble carbonates, phosphates, & oxalates produce precipitation. /Ferrous salts/
