Ammonium Carbonate Formula

Ammonium Carbonate Formula

This article describes the ammonium carbonate formula, often known as Baker’s ammonia formula or diammonium salt formula. It’s a chemical compound composed of ammonium and carbonate ions. The chemical or molecular formula for ammonium carbonate is (NH4)2CO3.

It is a colourless crystalline solid or white powder with a strong ammonia odour and a sharp ammoniacal taste. It is not flammable and is soluble in water. When it interacts with acids, it produces ammonium salts and CO2. When it combines with bases, it creates ammonia. It is generated by combining carbon dioxide with aqueous ammonia.

It is commonly used as a leavening agent and smelling salt due to its ability to degrade to gaseous ammonia and carbon dioxide when heated.

Structural Formula Of Ammonium Carbonate (Baker’s Ammonia)

The Ammonium Carbonate Formula is (NH4)2CO3. When dissolved in water, ammonium carbonate is also non-combustible and soluble. It is significant that when it interacts with the acids, ammonium salt and carbon dioxide are simultaneously produced. Ammonia gas is created when it combines with bases. It is produced when aqueous ammonia and carbon dioxide are combined. Additionally, it is frequently employed as a flavouring agent and a leavening agent. This is due to its tendency to degrade upon heating into gaseous ammonia and carbon dioxide.

 Properties Of Ammonium Carbonate (Baker’s Ammonia)

The Ammonium Carbonate Formula (NH4)2CO3 is used in equations. The molecular weight is 96.09 g/mol as well. 1.50 g/cm3 describes the density. Its melting point decomposes while its boiling point decomposes.

Ammonium Carbonate Formula

The Ammonium Carbonate Formula is (NH4)2CO3. It is a white, crystalline salt. It is an ammonium- and carbonate ion-containing chemical molecule. Ammonium Carbonate’s chemical or molecular formula is (NH4)2CO3, i.e., the Ammonium Carbonate Formula. It has a sharp ammonia flavour and is a colourless, crystalline solid or white powder with a strong ammonia odour. It is soluble in water and non-combustible. It produces carbon dioxide and ammonium salt when it reacts with acids. Ammonia gas is created when it combines with bases. Aqueous ammonia and carbon dioxide are combined to create it. It is frequently used as a leavening agent and as a smelling salt due to its ability to degrade into gaseous ammonia and carbon.


Carbon dioxide and aqueous ammonia are combined to create ammonium carbonate. Carbon dioxide can be used to make the Ammonium Carbonate Formula. This entails injecting ammonia and carbon dioxide gas with a purity level of 99–99.99% into two buffer gas vats at a pressure of 0.2–2MPa. To produce the Ammonium Carbonate Formula, open the valves on the vats to let the gas flow from the Rota metre into the sealed PVC synthesis reaction bag. Wherein, for carbon dioxide and ammonia gas individually, the flow rates are (0.6-2) X 106L/h and (0.1-0.6) X 106L/h, respectively.


There are two methods through which the ammonium carbonate breaks down at a very slow rate under standard pressure and temperature. As a result, any ammonium carbonate sample that was previously pure will quickly transform into a mixture that contains different byproducts. It is possible for ammonium carbonate to spontaneously break down into ammonium bicarbonate and ammonia.

NH4HCO3 + NH3 = (NH4)2CO3

which later break down into carbon dioxide, water, and some other ammonia molecules.

CO2 + NH3 + H2O = NH4HCO3  


The smelling salts’ major ingredient is ammonium carbonate, which has (NH4)2CO3 as its Ammonium Carbonate Formula. Although their production procedure is on a lesser commercial scale. Ammonium carbonate is one of the active ingredients in the Canadian cough medicine Buckley’s that helps alleviate bronchitis symptoms. Additionally, certain traditional recipes, especially those from northern Europe and Scandinavia, use ammonium carbonate as a leavening agent.

Solved Example on Ammonium Carbonate Formula

Question- Which will not precipitate after adding ammonium carbonate while NH4CI is present? – (Mg), (Ba), (Ca), (Sr)

Solution: The salt solution of NH4Cl and NH4OH precipitates the carbonates of Ba2+, Sr2+, and Ca2+ when the Ammonium Carbonate Formula (NH4)2CO3 is added.

 BaCl2+(NH4)2CO3 → BaCO3↓+ 2NH4Cl

SrCl2+(NH4)2CO3 → SrCO3↓+ 2NH4Cl

CaCl2+(NH4)2CO3 → CaCO3↓+ 2NH4Cl

Then the answer is (1) – Mg.
