Ammonium Sulphite – 500 gram Packs

Ammonium Sulphite is an inorganic ammonium salt used in laboratory experiments involving sulphite ions, aqueous chemical reactions, and selected reducing processes. Available in a convenient 500 gram pack, it is suitable for reagent preparation, analytical investigations, and educational laboratory work where ammonium sulphite is specified. The compound is relevant to studies of ionic reactions and sulphite chemistry under controlled laboratory conditions. As sulphite salts can release sulphur dioxide upon contact with acids, appropriate ventilation and careful handling are essential. Lab Wale supplies Ammonium Sulphite for laboratory and research applications in LR Laboratory Reagent grade. Before use, verify the required chemical form and product specifications against your experimental method. Follow appropriate laboratory safety procedures for handling, storage, and disposal to help maintain a safe and organised working environment.

Description

Ammonium Sulphite is an inorganic salt containing ammonium cations and sulphite anions. The anhydrous compound has the molecular formula (NH₄)₂SO₃ and a molecular weight of approximately 116.14 g/mol. It is generally described as a white crystalline solid and is used in selected laboratory procedures involving sulphite chemistry. Its applications include preparation of specified reagent solutions and investigations of ionic reactions. The compound may be sensitive to storage conditions, and acidification can release sulphur dioxide gas. This 500 gram pack is intended for laboratory use where the chemical form and grade are appropriate. Confirm the supplied product details and the requirements of your method before preparing solutions or conducting experiments.

FAQs

1. What is the chemical formula of Ammonium Sulphite?

The formula for anhydrous Ammonium Sulphite is (NH₄)₂SO₃, and its molecular weight is approximately 116.14 g/mol. Its commonly listed CAS number is 10196-04-0. Confirm the supplied form on the product label before calculating quantities or preparing laboratory solutions.

2. What are the laboratory uses of Ammonium Sulphite?

Ammonium Sulphite is used in selected reagent preparations and chemical investigations involving sulphite ions. It may support experiments involving aqueous reactions and sulphite chemistry. Its suitability depends on the procedure, required purity, and chemical form specified for the application.

3. Does Ammonium Sulphite react with acids?

Yes. Acidification of sulphite salts can release sulphur dioxide gas, which can irritate the respiratory system. Such reactions should only be carried out using appropriate laboratory ventilation and safety controls. Avoid conducting acid–sulphite reactions in enclosed or poorly ventilated spaces.

4. What is the pack size and grade of this product?

This listing is for a 500 gram pack of Ammonium Sulphite designated LR Laboratory Reagent grade. Check the product label and supplied specifications to ensure that the chemical form and assay meet the requirements of your intended laboratory procedure.

5. What precautions should be followed when handling Ammonium Sulphite?

Wear appropriate gloves, protective eyewear, and a laboratory coat. Avoid inhaling dust and prevent contact with eyes and skin. Keep the chemical away from acids, use adequate ventilation, and follow your laboratory’s safety procedures and the applicable product safety documentation.

Storage Conditions

Store Ammonium Sulphite in a tightly closed, clearly labelled container in a cool, dry, well-ventilated location. Protect it from moisture and contamination, and keep it away from acids and other incompatible materials. Minimise unnecessary exposure to air during dispensing and close the container promptly after use. Follow the product-specific storage guidance and established laboratory chemical-storage procedures to help maintain the material’s suitability for its intended use.

Precautions for Handling

Handle Ammonium Sulphite using standard laboratory safety practices. Wear suitable chemical-resistant gloves, protective eyewear, and a laboratory coat. Avoid creating or inhaling dust, and prevent contact with eyes and skin. Use appropriate ventilation, especially when procedures involve acids, because sulphur dioxide gas may be released. Do not mix the reagent with other chemicals unless the procedure has been reviewed for safety. Keep food and drink out of the work area, wash hands after handling, and dispose of spills and waste according to established laboratory procedures and applicable regulations.
