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 following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

Ammonium bicarbonate is an inorganic compound with formula (NH 4)HCO 3. The compound has many names, reflecting its long history. Chemically speaking, it is the bicarbonate salt of the ammonium ion. It is a colourless solid that degrades readily to carbon dioxide, water and ammonia.
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.
Europium(III) carbonate can be obtained by mixing and heating an aqueous solution of ammonium carbonate and europium(III) chloride. [2] A saturated carbon dioxide ammonium carbonate solution (obtained from the reaction of hydrochloric acid and ammonium carbonate solution) can also precipitate europium carbonate from a europium salt solution.

The carbonate pump is sometimes referred to as the “hard tissue” component of the biological pump. [12] Some surface marine organisms, like Coccolithophores, produce hard structures out of calcium carbonate, a form of particulate inorganic carbon, by fixing bicarbonate. [13] This fixation of DIC is an important part of the oceanic carbon cycle.
