Everything about Ammonium Bicarbonate

Ammonium Bicarbonate: As we all have a good understanding of baker’s ammonia in daily life, employed within the cooking area for creating tasty, crunchy baked cookies or crackers biscuits, it’s also used in fast cooking. In contemporary chemistry, we call it chemically “ammonium bicarbonate”. Ammonium bicarbonate is an old term generally described and changed with other substances like Cooking powder (leavening) or baking soda (saleratus). It’s essential to indicate that baker’s ammonia is different from home ammonia, which could be hazardous.

What is Ammonium Bicarbonate?

It is an inorganic chemical substance that’s slightly standard. It includes the ammonium cation as well as the result of the bicarbonate anion. Chemically it is the bicarbonate salt (HCO-3) of ammonia (NH +4). It’s solid with no colour and quickly deteriorates to ammonia, carbon dioxide, and water.

Carbon dioxide: One in all the heavy colourless gas which is created by the burning of plants or pets issue. Its declaration is CO2 and likewise acidic with soluble in water. CO2 happens naturally in the earth’s environment as signed up with by the trace gas.

Ammonia: Ammonia might be a colourless, highly annoying gas with a poignant scent and suffocating smell. Its formula is NH3. 80% of the ammonia created by industry is used in agriculture as plant foods. Ammonia is likewise used to produce plastics, dynamites, fabrics, chemicals, dyes, and other chemicals. It’s additionally used as a cooling agent gas to filtrate water products.

Water: Water is developed from hydrogen as well as oxygen, and it exists in gaseous, liquid, as well as solid states. Water is one of the foremost abundant and crucial compounds, happening as a liquid in the world’s surface area under normal conditions. Its chemical formula is water with a molecular mass of eighteen.

This substance has several names which reflect its lengthy background, such as:

Ammonium hydrogen carbonate

Monoammonium carbonate

Monoammonium salt, and so on.

Chemical formula as well as Molecular formula

The chemical formula of is NH4HCO3.

The molecular formula of ammonium bicarbonate is CH5NO3.

Molar Mass: It has molar mass of 79.056 g/mol.

Look and also Melting Point: White crystalline solid with a melting point of 41.9 ° C. Framework.

Its chemical structure comprises the ammonium cation NH4+ and the bicarbonate anion HCO3–.


Ammonium bicarbonate is present throughout a small quantity in nitrogenous organic matter, together with several other ammonium salts. It also usually happens as a rare mineral called “Teschemacherite”.


Ammonium bicarbonate is created by combining two things that are co2 greenhouse gas as well as ammonia:

CO2 + NH3 + H2O = (NH4) HCO3.

As ammonium bicarbonate is unpredictable thermally, the reaction solution is always kept under a cold temperature. Therefore, this ends up allowing the precipitation of the merchandise as a white solid. Regarding 100,000, it generated heaps similarly within the year 1997.

Ammonia gas is sent to a solution (aqueous) of sesquicarbonate that’s a 2:1:1 combination of (NH4) HCO3, (NH4) 2CO3 and water transform it right into a traditional ammonium carbonate (( NH4) 2CO3), which might be acquired within the crystalline problem from a solution or preparation produced at about 30 ° C of temperature. Exposure to this substance to air offers off ammonia and reverts it to ammonium bicarbonate.

Salt of Hartshorn: Compositions including carbonate of ammonium have long been understood. They were once created commercially, formerly referred to as a spirit of ammonia or salt of hartshorn. It was obtained by dry purifying nitrogenous organic matter like hair, horn, and natural leather. In addition to ammonium bicarbonate, this material consists of ammonium carbamate (NH4CO2NH2) and ammonium carbonate (( NH4) 2CO3). It’s often called ammonium sesquicarbonate. It breaks down a solid ammoniacal smell, and on digestion with alcohol, the carbamate is entirely liquified, leaving a byproduct of ammonium bicarbonate. The same decomposition happens when the sesquicarbonate is subjected to air.

Physical Properties

It can specify physical properties of ABC( Ammonium Bicarbonate) as adhering to;

Ammonium bicarbonate is a solid white crystalline lug with a thickness of 1.59 g/mL and a temperature level of 41.9 ° C.

It has a robust scent of ammonia, and also it’s highly soluble in water.

It has an observing pungent odour.

Chemical Properties

The chemical properties of ABC (Ammonium Bicarbonate) will be stated as follow;

It dissolves with the water to produce a slightly alkaline solution.

Moreover, it’s insoluble in many chemical and organic solvents.

While it’s stable at about 25 ° C, it decays at a temperature over 36 ° C to form ammonia, carbon dioxide or greenhouse exhaust, and water in a type of endothermic response. Additionally, it takes in the energy for the reaction from the atmosphere.

NH4HCO3 = NH3+ CO2+ H2O

It reacts with acids to produce carbonic acid gas and also reacts with the bases to supply ammonia.

Uses of Ammonium Bicarbonate

Following are the important business and also general uses of ammonium bicarbonate:

  • As a raising agent for food or baked products like biscuits, cookies, and cream-puff doughs within the food industry.
  • Making porous plastics, ceramics, dyes, and pigments.
  • It can be used for range removal in boilers and creating a foaming agent for rubber.
  • It gets rid of the gypsum from heat exchangers and processing devices.
  • She contributed to the compost pile to increase the disintegration rate and use them as plant foods.
  • Due to its unstable nature, it is a straightforward barrier (due to its dangerous nature) in pharmaceutical applications like lyophilization (freeze-drying) for producing injectable and oral dosage types.
  • Used as an item for human as well as veterinary drugs
  • Ammonium bicarbonate is used as leavening in some food or food preparation applications.
  • Better, we likewise utilize it within cough medicine and as an antacid.
  • We also use it as plant food, pH barrier, and reagent within the chemical laboratories. In the sectors, we use it in producing dyes, pharmaceuticals, catalysts, ceramics, plastics, and numerous other products.
  • It is likewise helpful for buffering services to form them alkaline throughout the chemical purification instead of the high-performance fluid chromatography. This allows the recovery of the substance of interest by freeze-drying.

Ammonium Bicarbonate is a widely utilized component in the bakery industry due to its leavening, stabilizing properties, and acid controling ability.

Typical applications of Ammonium Bicarbonate:




Icy milk products

Bakery components

Pigments and also paints


Fire extinguishers

A leavening agent is a compound that releases gas in baked goods to convey a light appearance.

Ammonium Bicarbonate properties

bicarbonato-de-amonio2Ammonium Bicarbonate is an inorganic compound, chemically talking. It is the bicarbonate salt of the ammonium ion. Thanks to its physicochemical properties, this component is used as a leavening, maintaining agent and as a level of acidity regulatory authority.

The supporting property of Ammonium Bicarbonate enables maintaining the perfect physicochemical properties in food, either protecting food in a constant state or by keeping/ heightening a shade.

Besides, it has the property of managing the pH by controlling or customizing the acidity or alkalinity of a food.

Ultimately, as a raising agent, Ammonium Bicarbonate, alone or in combination with others, can release gas and, at the same time, raise batter and also dough volume for baked products.

Referrals about Ammonium Bicarbonate

Ammonium Bicarbonate and Sodium Bicarbonate are the most common ingredients used as leavening agents in the bakery industry because they launch carbon dioxide when specific temperature and moisture problems are reached.

  • When it is used, it disintegrates over 40 ° C, releasing CO2, H2O and NH3. Other chemical leavening agents are added to avoid any trace of ammonia in the items.
  • For Ammonium Bicarbonate, an Acceptable Daily Consumption (ADI) is not defined by the Joint FAO/WHO Specialist Board on Food Additives (JECFA) since its use does not represent a danger to food security.
