Ammonium Carbonate 30.5+% NH3, Food Grade FCC

What is Ammonium Carbonate?

Ammonium carbonate, (NH4)2CO3 H2O, forms water-soluble, colorless, cubic crystals. From 58 °C it completely decomposes into ammonia, carbon dioxide and water.

The salt forms a colorless crystal with a faint smell of ammonia. It has a density of about 1.6 g cm−3 (at 20 °C). In aqueous solution, this salt, which has a weak acid as cation and a weak base as anion, is somewhat basic. The pH value is the result of a complex equilibrium that develops between dissolved ammonia NH3, ammonium ions NH4+, carbonate ions CO32−, hydrogen carbonate ions HCO3− and carbon dioxide CO2 as a result of salt hydrolysis. The pH of a 10% aqueous solution of ammonium carbonate is 9.4.

The ammonium carbonate salt reacts to hydrogen carbonate and hydroxide ions during dissolution in water. An aqueous solution of ammonium carbonate is therefore only stable in a neutral and weakly basic environment - when strong acids are added gaseous carbon dioxide escapes, when concentrated alkalis are added ammonia gas escapes.

When dry, ammonium carbonate decomposes slowly in air, but decomposes violently when heated.

What is Ammonium Carbonate Used For?

Ammonium carbonate is used in the synthesis of heterocycles and as an additive in photographic developers. It is also used in dyeing as a stain, as a staining agent, and as a carbon dioxide generator in fire extinguishers.

It is also used as a leavening agent (as a component of staghorn salt). In the EU it is approved as a food additive with number E 503i.

It was also used in the past as a smelling salt to stimulate dizziness and fainting.

Ammonium carbonate is commonly used in inorganic chemistry for a qualitative analysis to separate the alkaline earth metal cations of barium, strontium and calcium as a group from an unknown sample in the cation separation process and identify them using detection reactions.

It is also used to make catalysts, foams, hair treatment products, and casein paints and adhesives.
