Ammonium Carbonate

Ammonium carbonate is a chemical compound that has consists of ammonia and carbonate ions. It is a colourless crystalline solid and has a sharp ammonium smell agent. It is acidic in nature and acts as basic. It is soluble in water and non combustible substances.The systematic IUPAC name is known as ammonium carbonate. The chemical or molecular formula of ammonium carbonate is  (NH4)2CO3. It is also known as bakers ammonia.

Structural Formula

This is the structural formula of the ammonium carbonate:

Ammonium Carbonate

Chemical Formula

The chemical formula of the ammonium carbonate is (NH4)2CO3.

Preparation Method

When the ammonia is reacts with the carbon dioxide in the aqueous form it gives the results of ammonium carbonate. Further it can be decomposed to the ammonium bicarbonate and ammonia. It also crystallizes in an ammonium solution to exposed in the carbon dioxide rich atmosphere.

(NH4)2CO3 → NH4HCO3 + NH3

NH4HCO3 → H2O + CO2 + NH3
