Ammonium Acetate Formula

Ammonium Acetate Formula

Ammonium bicarbonate is an inorganic substance, and the Ammonium Bicarbonate Formula is (NH4)HCO3, which is simplified to NH5CO3. The numerous names given to this substance reflect its lengthy history. Chemically, it is the bicarbonate salt of the ammonium ion. It is a colourless substance that breaks down into carbon dioxide, ammonia, and water. It is a somewhat basic inorganic chemical. The Ammonium Bicarbonate Formula is NH4HCO3 at the molecular level. It has the appearance of being a solid white crystal.

Ammonia can be clearly smelled. While easily dissolving in water, it is insoluble in the majority of other organic solvents. An alkaline solution is produced when ammonium bicarbonate is dissolved in water. It is made up of the bicarbonate anion and the ammonium cation. At the molecular level, NH4HCO3  is the formula of Ammonium Bicarbonate Formula. It resembles a solid white crystal and smells strongly like ammonia. While easily dissolving in water, it is insoluble in the majority of other organic solvents. The result of dissolving ammonium bicarbonate in water is a solution that has a mildly alkaline pH.

Properties Of Ammonium bicarbonate Formula

The Ammonium Bicarbonate Formula is NH4HCO3 with a molecular weight of 79.056 g/mol. It has a density of 1.586 g/cm3. It appears to be a crystalline white solid.The melting point is 41.9 °C.

Physical Properties

A white crystalline solid with a density of 1.59 g/mL and a melting point of 41.9 °C is ammonium bicarbonate. It is very soluble in water and has a strong ammonia odour.

Chemical Properties

It disintegrates in the water and produces a slightly alkaline solution. It is also insoluble in a variety of organic solvents. It decomposes at a temperature above 36 °C in an endothermic reaction to produce ammonia, carbon dioxide, and water while being stable at room temperature, which is close to about 25 °C. Additionally, it draws energy for the reaction from the immediate surroundings.

Use Of Ammonium bicarbonate 

The Ammonium Bicarbonate Formula NH4HCO3 has various uses. Baking powder (ammonium bicarbonate) is used in a variety of food preparation and culinary processes.Additionally, it is used as an antacid and in cough syrups. In the chemical laboratory, the Ammonium Bicarbonate Formula is also used as a reagent, pH buffer, and fertiliser. It is used in the production of dyes, medications, catalysts, ceramics, polymers, and a variety of other goods.

Similar to high-performance liquid chromatography, the Ammonium Bicarbonate Formula is also helpful for buffering solutions to make them alkaline during the chemical purification. By using freeze-drying, the compound of interest can be recovered.

Formula and Structure

The Ammonium Bicarbonate Formula has the chemical formula NH4HCO3. Ammonium bicarbonate has the chemical formula CH5NO3 and a molar mass of 79.056 g/mol. It is chemically composed of the bicarbonate anion HCO3- and the ammonium cation NH4+.


In addition to several other ammonium salts, nitrogenous organic matter also contains a minor amount of ammonium bicarbonate.


In order to create ammonium bicarbonate, carbon dioxide and ammonia must be combined.

(NH4)HCO3: CO2 + NH3 + H2O

The reaction solution is kept at a low temperature because ammonium bicarbonate is thermally unstable. Therefore, this leads to the product precipitating as a white solid.


They create ammonium bicarbonate by introducing carbon dioxide gas into aqueous ammonia and waiting for the crystals to form before removing them from the solution using centrifugation or filtration. The reaction happens at a cool temperature to stop the product from decomposing.

CO2 + NH3 + H2O NH4HCO3


This substance is used as a component of medicines, dyes, pigments, and fire-extinguishing chemicals. It is also an important fertiliser because it is a source of ammonia, which is used in fertiliser production.It is still frequently used in the production of ceramics, chrome leather tanning, the synthesis of catalysts, and the plastics and rubber industries. 

Health Effects/Safety Hazards

The Ammonium Bicarbonate Formula NH4HCO3 is not dangerous in low quantities. Additionally, its breakdown reaction, which produces pungent ammonia gas and is a strong irritant, is its most frequent and significant health risk. Similar to this, breathing in ammonium bicarbonate can cause severe coughing and breathing difficulties, as well as irritation of the eyes, nose, skin, and entire respiratory system.

Solved Examples on Ammonium Bicarbonate Formula

When the solvent (water) is being purged with regular air or CO2 gas, how can the bicarbonate concentration be measured?

 Solution: Depending on how precise the outcome needs to be, there are a few possibilities.

When measuring the pH change along with system modelling, one can get a good approximation if they know the beginning pH and are using pure water. They can also take a sample of their solution, add a base to it, and then titrate between the two pK values of H2CO3. Additionally, they could make their samples alkaline or add Ba. After drying, they can weigh the BaCO3.
