[hide]Properties
Chemical
Nickel(II) perchlorate will form complex with amines, which are powerful energetic compounds.
Physical
Nickel(II) perchlorate is a greenish hygroscopic solid, soluble in water.
Availability
Nickel(II) perchlorate is sold by chemical suppliers.
Preparation
Can be prepared by reacting nickel(II) oxide with perchloric acid, followed by recrystallization.
- NiO + 2 HClO4 → Ni(ClO4)2 + H2O
Another route involves adding a solution of nickel(II) sulfate in a solution of barium perchlorate:
- NiSO4 + Ba(ClO4)2 → Ni(ClO4)2 + BaSO4↓
This route produces the hexahydrate form. Anhydrous nickel perchlorate cannot be produced by heating nickel(II) perchlorate hexahydrate, since it decomposes upon heating.
Projects
- Make tris(ethylenediamine)nickel perchlorate[1]
- Make nickel hexamine perchlorate
- Make nickel hydrazine perchlorate
Handling
Safety
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.
Storage
In closed plastic (HDPE or PTFE) or glass bottles, in a dry place, away from combustible materials and metallic powders.
Disposal
Nickel perchlorate should be reduced to chloride, then precipitated into an insoluble form and taken to waste disposal centers.
