What is Nickel Nitrate? 🧪
Nickel nitrate is an inorganic compound with the chemical formula Ni(NO₃)₂. This compound is a bright green crystalline salt that is highly soluble in water. Nickel nitrate is typically found in two different hydrates, namely nickel nitrate hexahydrate (Ni(NO₃)₂·6H₂O) and nickel nitrate trihydrate (Ni(NO₃)₂·3H₂O).
Chemical Composition of Nickel Nitrate 🧬
To better understand nickel nitrate, let's break down its chemical composition:
- Nickel (Ni): The central metal of the compound, nickel, is a transition metal known for its corrosion resistance and catalytic properties.
- Nitrate (NO₃): This is a polyatomic ion made up of one nitrogen atom (N) and three oxygen atoms (O). Nitrate ions are commonly found in fertilizers and can affect plant growth.
The complete formula can be broken down as follows:
- Nickel: 1 atom
- Nitrogen: 2 atoms (from 2 nitrate ions)
- Oxygen: 6 atoms (from 2 nitrate ions)
The molecular weight of nickel nitrate hexahydrate is approximately 290.79 g/mol.
