Ammonium Nickel Sulphate – 500 gram Packs

Ammonium Nickel Sulphate is an inorganic double salt containing ammonium, nickel(II), and sulphate ions. The name commonly refers to Ammonium Nickel Sulphate Hexahydrate, with the chemical formula (NH₄)₂Ni(SO₄)₂·6H₂O and a molecular weight of approximately 394.99 g/mol. This compound generally appears as green to pale bluish-green crystalline material and is used in inorganic chemistry experiments, coordination chemistry investigations, and selected analytical procedures involving nickel compounds. It is relevant to college and university laboratory practicals, materials-related research, and studies of transition-metal salts and their chemical reactions. Ammonium Nickel Sulphate can support investigations into nickel(II) ion behaviour and the properties of hydrated double salts. Its suitability for a particular procedure depends on the required reagent specifications and experimental method. Because nickel compounds can present significant health and environmental hazards, appropriate laboratory controls and responsible waste management are essential.

Frequently Asked Questions About Ammonium Nickel Sulphate

What is Ammonium Nickel Sulphate used for in laboratories?

Ammonium Nickel Sulphate is used in inorganic chemistry practicals, nickel(II) ion investigations, coordination chemistry studies, and selected crystal chemistry research. It can provide a nickel-containing starting material for appropriate experiments. Its use should be restricted to procedures with suitable safety controls because nickel compounds can present significant health hazards.

What are the molecular formula and molecular weight of Ammonium Nickel Sulphate Hexahydrate?

The molecular formula is (NH₄)₂Ni(SO₄)₂·6H₂O, and its empirical formula is H₂₀N₂NiO₁₄S₂. The molecular weight is approximately 394.99 g/mol. The formula includes six water molecules of crystallization, so the anhydrous compound has a different formula mass.

What is the CAS number of Ammonium Nickel Sulphate Hexahydrate?

The CAS Registry Number for Ammonium Nickel Sulphate Hexahydrate is 7785-20-8. It is also called ammonium nickel(II) sulphate hexahydrate or nickel ammonium sulphate hexahydrate. Confirming the CAS number helps distinguish the hydrated double salt from other nickel sulphate and ammonium sulphate compounds.

What precautions are necessary when using Ammonium Nickel Sulphate?

Nickel compounds can be harmful if swallowed or inhaled, may cause allergic reactions, and may present chronic health hazards. Use suitable gloves, protective clothing, and safety goggles, and avoid generating dust. Handle the reagent under appropriate ventilation and follow institutional safety procedures, including controls for nickel-containing waste.

How should Ammonium Nickel Sulphate be stored?

Store Ammonium Nickel Sulphate in a tightly closed, compatible, clearly labelled container in a cool, dry, well-ventilated area. Avoid excessive heat, dust formation, and contact with incompatible chemicals such as strong oxidizing agents. Keep it secured against unauthorised access and follow the current Safety Data Sheet for specific storage and segregation requirements.

Storage Conditions for Ammonium Nickel Sulphate

Store Ammonium Nickel Sulphate Hexahydrate in a tightly closed, compatible container in a cool, dry, well-ventilated location at the recommended ambient temperature. Protect the material from contamination and excessive heat, and keep it separated from incompatible substances, including strong oxidizing agents. Store nickel-containing reagents in clearly labelled containers with appropriate access controls, and prevent spills or releases into drains and the environment.

Precautions for Handling Ammonium Nickel Sulphate

Review the current Safety Data Sheet and institutional risk assessment before use. Wear suitable chemical-resistant gloves, protective clothing, and safety goggles, and avoid inhaling dust or allowing the material to contact the skin and eyes. Use appropriate ventilation and minimise dust generation. Nickel compounds may cause sensitisation and serious long-term health effects, so restrict access to trained personnel, prevent environmental release, and collect all nickel-containing waste for disposal through approved hazardous-waste procedures.
