Potential Exposure
Ferric ammonium oxalate is used in
photography and making blueprints
First aid
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit. The
symptoms of metal fume fever may be delayed for
412 hours following exposure: it may last less than
36 hours.

Incompatibilities
Incompatible with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine,
bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases,
strong acids, oxoacids, epoxides. Strong oxidizers may cause
release of toxic phosphorus oxides. Organophosphates, in the
presence of strong reducing agents such as hydrides, may
form highly toxic and flammable phosphine gas. Keep away
from alkaline materials.
Chemical Properties
Ferric ammonium oxalate is a green crystalline, solid with a granular or salt-like appearance. Color
depends on level of iron present
Chemical Properties
yellow-green crystals
Uses
Ammonium iron(III) oxalate trihydrate is used in the preparation of Langmuir-Blodgett magnetic thin films. It is also involved in the production of blueprint paper.
General Description
Ammonium ferric oxalate trihydrate decomposes completely at 275°C giving Fe2O3 and has been investigated by thermogravimetry and differential thermal analysis.
Purification Methods
Crystallise it from hot water (0.5mL/g). [Beilstein 3 III 1103.]
