Ammonium Nickel(II)Sulfate Hexahydrate(CAS: 7785-20-8)

Ammonium Nickel(II) Sulfate Hexahydrate, also known as Ni(NH4)SO4·6H2O, is a crystalline solid with a white or light yellow color. Its molecular weight is approximately 308.78 g/mol. It is soluble in water and slightly soluble in ethanol. Chemically, it is a strong electrolyte and exhibits low reactivity under normal conditions. It can be oxidized in air, but this reaction is not common under standard laboratory conditions.

Ammonium Nickel(II) Sulfate Hexahydrate is commonly synthesized by reacting nickel(II) sulfate with ammonium sulfate in water. The process involves dissolving nickel(II) sulfate and ammonium sulfate in water, followed by crystallization from the solution, typically by concentration or cooling. This method allows for high purity and controlled crystallization.

Ammonium Nickel(II) Sulfate Hexahydrate finds applications in various industries, including pharmaceuticals for chelation therapy, sensors for detecting metal ions, and as a catalyst in certain organic synthesis reactions. It is also used in the production of nickel-based alloys and as a reagent in analytical chemistry.

When handling Ammonium Nickel(II) Sulfate Hexahydrate, it is important to wear appropriate personal protective equipment (PPE), including gloves and safety goggles. It should be handled in a well-ventilated area or a fume hood to avoid inhalation. In case of a spill, it should be cleaned up carefully to avoid skin contact or inhalation. Refer to the safety data sheet (SDS) for detailed handling and disposal instructions.
