The reaction Fe + Ni(OH)₂ → Ni + Fe(OH)₃ is an example of a redox reaction where iron (Fe) is oxidized, and nickel hydroxide (Ni(OH)₂) is reduced. In this process, iron donates electrons, leading to the formation of iron(III) hydroxide (Fe(OH)₃), while nickel is reduced to its elemental form. This indicates that iron has a higher tendency to oxidize compared to nickel in this context. Overall, the reaction showcases the principles of electron transfer and the relative reactivity of the metals involved.
In a single replacement reaction, iron (Fe) can replace nickel (Ni) in nickel(II) chloride (NiCl₂) because iron is more reactive than nickel. The reaction can be represented as: [ \text{NiCl}_2 + \text{Fe} \rightarrow \text{FeCl}_2 + \text{Ni} ] This produces ferrous chloride (FeCl₂) and solid nickel (Ni) as products.
Some examples are: Mn, Fe, Co, Ni, Cu. .
Ni (Nickel) has a larger atomic size than Fe (Iron). This is because Nickel has more electrons and energy levels, which leads to a greater atomic radius compared to Iron. Additionally, Nickel is located in the same period as Iron on the periodic table, but it is to the right of Iron, indicating a larger atomic size.
When Ni^2+ reacts with NH3, it forms a complex ion known as [Ni(NH3)6]^2+. This complex ion is stable and soluble in water.
Nickel(II) is the plus two (+2) oxidation state of nickel (Ni), and we write it Ni(II) or Ni++ when we set it down.
In a single replacement reaction, iron (Fe) can replace nickel (Ni) in nickel(II) chloride (NiCl₂) because iron is more reactive than nickel. The reaction can be represented as: [ \text{NiCl}_2 + \text{Fe} \rightarrow \text{FeCl}_2 + \text{Ni} ] This produces ferrous chloride (FeCl₂) and solid nickel (Ni) as products.
The solubility product constant (Ksp) for Ni(OH)2 is approximately 3.0 x 10^-16. This indicates the equilibrium between the dissolved nickel (II) ions and the undissolved nickel hydroxide solid.
The chemical symbol for iron is Fe and the chemical symbol for nickel is Ni.
