Potential Exposure
It is used in chemical analysis and to
make blueprint paper, explosives; a rust-removal ingredient
in metal polishes.
First aid
Move victim to fresh air. Call 911 or emergency
medical service. Give artificial respiration if victim is not
breathing. Do not use mouth-to-mouth method if victim
ingested or inhaled the substance; give artificial respiration
with the aid of a pocket mask equipped with a one-way
valve or other proper respiratory medical device.
Administer oxygen if breathing is difficult. Remove and
isolate contaminated clothing and shoes. In case of contact
with substance, immediately flush skin or eyes with running
water for at least 20 minutes. For minor skin contact,
avoid spreading material on unaffected skin. Keep victim
warm and quiet. Effects of exposure (inhalation, ingestion
or skin contact) to substance may be delayed. Ensure that
medical personnel are aware of the material(s) involved
and take precautions to protect themselves. Medical observation
is recommended for 24 to 48 hours after breathing
overexposure, as pulmonary edema may be delayed.
As first aid for pulmonary edema, a doctor or authorized
paramedic may consider administering a drug or other
inhalation therapy.

Incompatibilities
Ammonium oxalate is a reducing agent
and also reacts as a base to neutralize acids and reacts with
oxidizers generating carbon dioxide. Incompatible with oxidizers (chlorates, hypochlorite solutions, 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.
Chemical Properties
Ammonium oxalate (NH4)2C204, is a white solid soluble, formed by reaction of NH40H and oxalic acid, and then evaporating. Used as a source of oxalate; ammonium binoxalate NH4HC204·H20.
Chemical Properties
Ammonium oxalate is an odorless, colorless
crystalline material or powder.
Uses
Ammonium oxalate monohydrate can be used to study chelators, biological buffers and biochemicals and reagents. It has been used for the detection and determination of calcium, lead, fluoride, and rare earth metals. It is employed as chelators and forms complexes with metals. It acts as reducing agent in gold extraction and is an active ingredient of ferrous metal surface polishing fluid. It is a promoting agent in production of cobalt oxide and nickel oxide.
It has been used in an analysis of the effective segregation coefficient keff of different impurities, which suggested that the dehydration energies of cations mainly determine the capability of capture of impurity species by the growing crystal. It is widely utilized as a buffering reagent and a dispersant to determine the surface interaction of platelets.
Ammonium oxalate monohydrate is also a buffering reagent and a dispersant to determine the surface interaction of platelets and to investigate the formation of oxalate monoalkylamide in the human lens. Ammonium oxalate monohydrate has also been used to study its acute poisoning effect on sheep, and surely has many additional uses.
Uses
Used for the detection of calcium, lead, fluoride and a buffering agent
General Description
Ammonium oxalate monohydrate is a diammonium salt of oxalic acid. Its refined crystal structure has been investigated by three-dimensional diffraction studies. Influence of bivalent [Mn(II), Co(II), Ni(II)] and trivalent cations [Fe(III), Cr(III)] impurities on the growth rates of ammonium oxalate monohydrate crystals has been described. Its space group and unit cell parameters have been analyzed by neutron diffraction studies. Its IR spectra have been compared with that of isolated coal-solubilizing agent (CSA).
Purification Methods
Crystallise it from water (10mL/g) at 50o. [Beilstein 2 IV 1846.]
