Ammonium Hydrogen Sulphate – 500 gram Packs

Ammonium Hydrogen Sulphate, also known as ammonium bisulphate or ammonium hydrogensulphate, is an inorganic acidic salt with the chemical formula NH₄HSO₄ and a molecular weight of approximately 115.11 g/mol. It is formed by the partial neutralisation of sulphuric acid with ammonia and is commonly encountered as a white crystalline solid or powder. The compound is water-soluble and hygroscopic, and its aqueous solutions exhibit acidic properties. These characteristics make Ammonium Hydrogen Sulphate relevant to experiments involving acid–base chemistry, sulphate compounds, solution preparation, and chemical reactivity. It can be used in appropriate school and college chemistry practicals, university teaching laboratories, analytical investigations, and research procedures requiring an acidic ammonium salt. Its suitability for specific analytical methods depends on the required reagent specifications. Appropriate precautions are essential because the substance can cause severe skin burns and eye damage.

Frequently Asked Questions About Ammonium Hydrogen Sulphate

What is Ammonium Hydrogen Sulphate used for in laboratories?

Ammonium Hydrogen Sulphate is used in suitable experiments involving acidic salts, acid–base reactions, aqueous solution preparation, and inorganic chemistry. It may also support research into sulphate-containing chemical systems. Its suitability depends on the analytical method, required grade, and applicable laboratory safety procedures.

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

The molecular formula is NH₄HSO₄, and its empirical formula is H₅NO₄S. Its molecular weight is approximately 115.11 g/mol. These values identify the compound as ammonium hydrogen sulphate, which contains one ammonium ion and one hydrogen sulphate ion per formula unit.

What is the CAS number of Ammonium Hydrogen Sulphate?

The CAS Registry Number for Ammonium Hydrogen Sulphate is 7803-63-6. The compound is also known as ammonium bisulphate and ammonium acid sulphate. Checking the CAS number alongside the chemical name helps distinguish it from ammonium sulphate, which has a different formula and CAS number.

Why is Ammonium Hydrogen Sulphate considered an acidic salt?

Ammonium Hydrogen Sulphate is formed through partial neutralisation of sulphuric acid by ammonia. Its hydrogen sulphate ion can release a proton in aqueous solution, contributing to acidic behaviour. This property makes the compound useful for selected investigations of acid–base equilibria and the chemistry of acidic salts.

What precautions are necessary when handling Ammonium Hydrogen Sulphate?

Wear suitable chemical-resistant gloves, protective clothing, and safety goggles, and avoid inhaling dust or allowing the material to contact the skin or eyes. The substance can cause severe burns and eye damage. Use appropriate ventilation, keep the container closed, and follow the current Safety Data Sheet and institutional procedures.

Storage Conditions for Ammonium Hydrogen Sulphate

Store Ammonium Hydrogen Sulphate in a tightly closed, compatible container in a cool, dry, well-ventilated area at the recommended ambient storage temperature. Protect it from moisture because it is hygroscopic, and keep it away from incompatible materials, including strong oxidizing agents and metals where specified by the Safety Data Sheet. Avoid unnecessary heating and ensure the container remains securely closed between uses.

Precautions for Handling Ammonium Hydrogen Sulphate

Review the current Safety Data Sheet before handling Ammonium Hydrogen Sulphate. Wear suitable gloves, protective clothing, and chemical safety goggles, and avoid generating or inhaling dust. Prevent skin and eye contact, and use appropriate ventilation when weighing or preparing solutions. Avoid contact with incompatible chemicals and use established procedures for spill management and waste disposal. Because this substance can cause severe skin burns and eye damage, educational laboratory use requires appropriate supervision and suitable safety facilities.
