Ammonium Bicarbonate

Ammonium bicarbonate (NH₄HCO₃) is an ammonium bicarbonate salt. It appears as a white powder. This food additive dissolves in water, making it alkaline (basic). Ammonium bicarbonate is also referred to as ammonium acid carbonate or ammonium hydrogen carbonate.



Ammonium bicarbonate, also known as ammonium hydrogen carbonate, is a chemical compound with the chemical formula NH₄HCO₃.

Appearance: Ammonium bicarbonate typically appears as a white crystalline powder.


  • Food Industry: It is occasionally used as a leavening agent in baking, especially in the preparation of cookies, crackers, and other bakery products.
  • Chemistry: Employed in certain chemical processes and reactions. Fire Extinguisher: It can be utilized in some types of fire extinguishers.
  • Chemical Reactions: When heated, ammonium bicarbonate decomposes into ammonia (NH₃), carbon dioxide (CO₂), and water.


  • While ammonium bicarbonate is generally considered safe when used in appropriate quantities in foods, it's important to note that overconsumption can be harmful.
  • Prolonged inhalation of the ammonia vapor released during its decomposition can be irritating to the respiratory tract.
  • Storage: It should be stored in a dry, well-ventilated area away from heat sources.
  • Packaging: Typically available in securely sealed bags or containers.
  • Standards: Products intended for consumption must adhere to regulatory standards and meet quality requirements.
