Nickel(II) nitrate is the chemical compound with the formula Ni(ClO4)2. It is commonly available as the hexahydrate form, Ni(ClO4)2·6H2O.
Nickel(II) perchlorate will form complex with amines, which are powerful energetic compounds.
Nickel(II) perchlorate is a greenish hygroscopic solid, soluble in water.
Nickel(II) perchlorate is sold by chemical suppliers.
- NiO + 2 HClO4 → Ni(ClO4)2 + 2 H2O
- NiSO4 + Ba(ClO4)2 → Ni(ClO4)2 + BaSO4↓
This route produces the hexahydrate form. Anhydrous nickel perchlorate cannot be produced by heating nickle(II) perchlorate hexahydrate, since it decomposes upon heating.
- Make tris(ethylenediamine)nickel perchlorate
- Make nickel hexamine perchlorate
- Make nickel hydrazine perchlorate
Nickel(II) perchlorate is a powerful oxidizing agent. In contact with strong acids, it will ignite organic material on contact. If a cotton or paper is soaked in nickel perchlorate and left to dry, the resulting material will burn very rapidly in contact with open flame, almost explode.
Since it's a nickel compound, it is irritating to the eyes, skin, respiratory tract, and is also a known allergen and carcinogen.
In closed plastic (HDPE or PTFE) or glass bottles, in a dry place, away from combustible materials and metallic powders.
Nickel perchlorate should be reduced to chloride, then precipitated into an insoluble form and taken to waste disposal centers.
