Ammonium nickel sulfate ((NH4)2Ni(SO4)2) hexahydrate

Description:
Ammonium nickel sulfate hexahydrate, with the chemical formula (NH4)2Ni(SO4)2·6H2O and CAS number 7785-20-8, is a crystalline compound that typically appears as greenish or blue-green crystals. It is a double salt composed of ammonium ions and nickel sulfate, and it contains six water molecules of hydration. This compound is soluble in water, which makes it useful in various applications, including as a source of nickel in electroplating and as a catalyst in chemical reactions. The presence of nickel gives it unique properties, including potential toxicity, which necessitates careful handling. Ammonium nickel sulfate hexahydrate is also used in the preparation of nickel-based catalysts and in the production of nickel salts. Its thermal stability allows it to decompose upon heating, releasing ammonia and sulfur oxides. As with many nickel compounds, it is important to consider environmental and health safety guidelines when working with this substance.
