Ammonium Bicarbonate BP
(Ammonium Hydrogen Carbonate)
NH4HCO3 79.1 1066-33-7
DEFINITION
Ammonium Hydrogen Carbonate contains not less than 98.0 per cent and not
more than 101.0 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 60C. 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 50 mg in 2 ml of
water. The solution gives the reaction
of ammonium salts.
TESTS
Solution S
Dissolve 14.0 g in 100 ml of distilled
water. Boil to remove the ammonia, allow to cool and dilute to 100.0
ml with distilled water.
Chlorides
Dilute 5 ml of solution S to 15 ml with water. The solution
complies with the limit test for chlorides (70 ppm).
Sulphates
15 ml of solution S complies with the limit test for sulphates (70 ppm)
Iron
Dilute 1.8 ml of solution S to 10 ml with water. The solution
complies with the limit test for iron (40 ppm).
Heavy metals
Dissolve cautiously 2.5 g in 25 ml of 1 M hydrochloric acid. 12 ml of
the solution complies with limit test A for heavy metals (10 ppm)
Ammonium Bicarbonate FCC
NH4HCO3 Formula wt 79.06
INS: 503(ii) CAS: [1066-33-7]
DESCRIPTION
Ammonium Bicarbonate occurs as white crystals or as a crystalline
powder. It volatilizes rapidly at 60°, 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
99.0% and not more than 100.5% of NH4HCO3.
Chloride: Not more
than 0.003%.
Lead: Not more than
3 mg/kg.
Nonvolatile Residue: Not more than 0.05% (0.55% for products containing a suitable ant caking
agent).
Sulfur Compounds (as SO4): Not more than 0.007%.
