Synonyms: Ammonium hydrogen carbonate; Ammonium acid carbonate
CAS Number: ********7, Molecular Weight: *9.1, Chemical Formula:
NH4HCO3, EINECS EC Number: ********5
Ammonium Bicarbonate BP
(Ammonium Hydrogen Carbonate)
NH4HCO3 **- *9.1 **- ********7
DEFINITION
Ammonium Hydrogen Carbonate contains not less than *8.0 per cent
and not more than **1.0 per cent of the equivalent of ammonium
hydrogen carbonate.
CHARACTERS
A fine, white, crystalline powder or white crystals, slightly
hygroscopic, freely soluble in water, practically insoluble in
alcohol.
It volatilizes rapidly at *0C. The volatilization takes place
slowly at ambient temperatures if the substance is slightly moist.
It is in a state of equilibrium with ammonium carbamate.
IDENTIFICATION
A. It gives the reaction of carbonates and bicarbonates.
B. Dissolve *0 mg in 2 ml of water. The solution gives the reaction
of ammonium salts.
TESTS
Solution S
Dissolve *4.0 g in **0 ml of distilled water. Boil to remove the
ammonia, allow to cool and dilute to **0.0 ml with distilled
water.
Chlorides
Dilute 5 ml of solution S to *5 ml with water. The solution
complies with the limit test for chlorides (*0 ppm).
Sulphates
*5 ml of solution S complies with the limit test for sulphates (*0
ppm)
Iron<br>Dilute 1.8 ml of solution S to *0 ml with
water. The solution complies with the limit test for iron (*0
ppm).
Heavy metals
Dissolve cautiously 2.5 g in *5 ml of 1 M hydrochloric acid. *2 ml
of the solution complies with limit test A for heavy metals
(*0 ppm)
Ammonium Bicarbonate FCC Food Grade
NH4HCO3 Formula wt *9.*6
INS: **3(ii) CAS: [********7]
DESCRIPTION
It occurs as white crystals or as a crystalline powder. It
volatilizes rapidly at *0°, dissociating into ammonia, carbon
dioxide, and water, but it is quite stable at room temperature. One
gram dissolves in about 6mL of water. It is insoluble in
alcohol.
REQUIREMENTS
Identification: A sample gives positive tests for Ammonium
and for Bicarbonate.
Assay: Not less than *9.0% and not more than **0.5% of
NH4HCO3.
Chloride: Not more than 0.**3%.
Lead: Not more than 3 mg/kg.
Nonvolatile Residue: Not more than 0.*5% (0.*5% for
products containing a suitable ant caking agent).
Sulfur Compounds (as SO4): Not more than 0.**7%.
