Ammonium Hydrogen Carbonate – 500 gram Packs

Ammonium Hydrogen Carbonate, also known as ammonium bicarbonate, is an inorganic ammonium salt with the chemical formula NH₄HCO₃ and a molecular weight of 79.06 g/mol. It is a white crystalline solid that dissolves in water and releases ammonia, carbon dioxide, and water vapour upon heating. This thermal decomposition makes it useful for studying gas evolution, reversible chemical processes, and the behaviour of ammonium salts in controlled laboratory experiments. Ammonium Hydrogen Carbonate is relevant to school and college chemistry practicals, university teaching laboratories, analytical investigations, and research involving carbonate chemistry, solution preparation, and thermal reactions. Its aqueous solutions can be used in appropriate experimental procedures where ammonium and bicarbonate ions are required. Selection for a particular application should consider the specified grade, purity requirements, and experimental conditions.

Frequently Asked Questions About Ammonium Hydrogen Carbonate

What is Ammonium Hydrogen Carbonate used for in laboratories?

Ammonium Hydrogen Carbonate is used in inorganic chemistry experiments, acid–base investigations, aqueous reagent preparation, and studies of thermal decomposition. It can also be used in suitable analytical and research procedures involving ammonium or bicarbonate ions, provided its grade and specifications meet the requirements of the method.

What are the chemical formula and molecular weight of Ammonium Hydrogen Carbonate?

The molecular formula is NH₄HCO₃, and its empirical formula is CH₅NO₃. Its molar mass is approximately 79.06 g/mol. These values correspond to the anhydrous compound, which is the standard chemical form identified by CAS number 1066-33-7.

What is the CAS number of Ammonium Hydrogen Carbonate?

The CAS Registry Number for Ammonium Hydrogen Carbonate is 1066-33-7. It is also commonly called ammonium bicarbonate or ammonium hydrogencarbonate. Checking the CAS number alongside the chemical name helps distinguish this compound from ammonium carbonate and other related inorganic salts.

Why does Ammonium Hydrogen Carbonate decompose when heated?

Ammonium Hydrogen Carbonate is thermally unstable and decomposes on heating to form ammonia, carbon dioxide, and water vapour. This reaction makes it useful for studying gas evolution and thermal decomposition. Heating should be performed only under appropriate laboratory supervision and ventilation because the released gases can irritate the respiratory tract.

How should Ammonium Hydrogen Carbonate be stored and handled safely?

Keep the reagent in a tightly closed, compatible container in a cool, dry, well-ventilated location away from heat, strong acids, strong bases, and strong oxidizing agents. Avoid generating or inhaling dust, and wear suitable protective equipment. Consult the current Safety Data Sheet for detailed precautions and spill procedures.

Storage Conditions for Ammonium Hydrogen Carbonate

Store Ammonium Hydrogen Carbonate in a tightly closed, compatible container in a cool, dry, well-ventilated area. Protect it from excessive heat and moisture, and avoid storage temperatures above approximately 35 °C because decomposition can release ammonia. Keep it separated from strong acids, strong bases, and strong oxidizing agents. Follow the product-specific storage recommendations provided in the current Safety Data Sheet.

Precautions for Handling Ammonium Hydrogen Carbonate

Review the current Safety Data Sheet before use and wear suitable laboratory gloves, protective clothing, and safety goggles. Avoid inhaling dust and prevent contact with the eyes and skin. Use adequate ventilation, particularly during heating, because ammonia and carbon dioxide may be released. Do not mix the reagent with incompatible chemicals. Clean up spills using approved laboratory procedures and dispose of waste according to institutional rules and applicable regulations. Educational experiments should be conducted under appropriate supervision.
