Ammonium carbonate is a salt that readily degrades to gaseous ammonia and carbon dioxide upon heating, it is used as a leavening agent and also as smelling salt. Ammonium carbonate decomposes at standard temperature and pressure.

Carbonic acid, monoammonium salt, mixture with ammonium carbamate.
Monoammonium carbonate mixture with ammonium carbamate [8000-73-5].

Ammonium Carbonate consists of ammonium bicarbonate (NH 4HCO3) and ammonium carbamate (NH2COONH4) in varying proportions. It yields not less than 30.0 percent and not more than 34.0 percent of NH3.

Identification: When heated, it is volatilized without charring, and the vapor is alkaline to moistened litmus paper. A solution (1 in 20) effervesces with acids.
Residue on ignition: not more than 0.1%.
Chloride: Maximum 0.0035%.
Sulfate: A 2.0-g portion shows no more sulfate than corresponds to 0.10 mL of 0.020 N sulfuric acid (0.005%).
Heavy metals: the limit is 0.001%.

NOTE. This product is a mixture of variable proportions of ammonium bicarbonate and ammonium carbamate.

DESCRIPTION
Ammonium Carbonate occurs as a white powder or as hard, white or translucent masses. It consists of ammonium bicarbonate (NH4HCO3) and ammonium carbamate (NH2·COONH4) in varying proportions. On exposure to air it becomes opaque and is finally converted into porous lumps or a white powder of ammonium bicarbonate because of the loss of ammonia and carbon dioxide. One gram dissolves slowly in about 4 mL of water. Its solutions are alkaline to litmus.
Function: Buffer; leavening agent; neutralizing agent.

REQUIREMENTS
Identification: When heated, a sample volatilizes without charring, and the vapor is alkaline to moistened litmus paper. A 1:20 aqueous solution effervesces when an acid is added.
Assay: Not less than 30.0% and not more than 34.0% of NH3.
Chloride: Not more than 0.003%.
Lead: Not more than 3 mg/kg.
Nonvolatile Residue: Not more than 0.05%.
Sulfur Compounds (as SO4): Not more than 0.005%.

Ammonium Carbonate Suppliers:

They who love thee on this earth, keep calling on thee and chanting thy beads
Lest thou forgetest.

They assign the credit of their hard work to your blessings
They keep you amused.

They come to thy temple with baskets of fruits, as if you were a glutton
They deny the same to their children.

They offer you milk for a bath and burn the ghee
They hardly understand the meaning of it.

They bring gold and diamonds. They come with beating of drums
They love to advertise their offerings.

They offer you a small bribe as advance for booty, called lottery
They love to dream.

I do not bow down at your door
I do not bargain for booty
Your promise of the heaven does not lure me
Your hell-fire does not scare me
I do not even know the proper method of prayer
I do not offer any thing to you
Ages have gone by and I have not seen you my lord
Yet my love for you keeps waiting for you
