Ammonium bicarbonate is an inorganic compound with formula (NH 4)HCO 3. The compound has many names, reflecting its long history. The compound has many names, reflecting its long history. Chemically speaking, it is the bicarbonate salt of the ammonium ion.
In water solutions, the carbamate anion slowly equilibrates with the ammonium NH + 4 cation and the carbonate CO 2− 3 or bicarbonate HCO − 3 anions: [3] [4] [5] H 2 NCO − 2 + 2 H 2 O ⇌ NH + 4 + HCO − 3 + OH − H 2 NCO − 2 + H 2 O ⇌ NH + 4 + CO 2− 3. Calcium carbamate is soluble in water, whereas calcium carbonate is not.
At ordinary temperatures and pressures, ammonium carbamate exists in aqueous solutions as an equilibrium with ammonia and carbon dioxide, and the anions bicarbonate, HCO − 3, and carbonate, CO 2− 3. [8] [6] [9] Indeed, solutions of ammonium carbonate or bicarbonate will contain some carbamate anions too. H 2 NCO − 2 + 2H 2 O ⇌ NH + 4 ...
Ammonium carbonate is a chemical compound with the chemical formula [N H 4] 2 C O 3. It is an ammonium salt of carbonic acid. It is composed of ammonium cations [NH 4] + and carbonate anions CO 2− 3. Since ammonium carbonate readily degrades to gaseous ammonia and carbon dioxide upon heating, it is used as a leavening agent and also as ...

The bicarbonate ion (hydrogencarbonate ion) is an anion with the empirical formula HCO − 3 and a molecular mass of 61.01 daltons; it consists of one central carbon atom surrounded by three oxygen atoms in a trigonal planar arrangement, with a hydrogen atom attached to one of the oxygens.
Solid ammonium carbonate and ammonium bicarbonate salts partly dissociate to form NH 3, CO 2 and H 2 O vapour as follows: (NH 4) 2 CO 3 → 2 NH 3 + CO 2 + H 2 O NH 4 HCO 3 → NH 3 + CO 2 + H 2 O. The smelling salts release ammonia (NH 3) gas, which triggers an inhalation reflex.
A carbonate is a salt of carbonic acid, (H 2 CO 3), [2] characterized by the presence of the carbonate ion, a polyatomic ion with the formula CO 2− 3. The word "carbonate" may also refer to a carbonate ester , an organic compound containing the carbonate group O=C(−O−) 2 .
