a complex ion: [Ni(NH3)6]
When copper (Cu) reacts with nickel(II) nitrate (Ni(NO3)2), a single displacement reaction occurs. Copper displaces nickel from nickel(II) nitrate, resulting in the formation of nickel (Ni) and copper(II) nitrate (Cu(NO3)2). The balanced products of the reaction are Ni(s) and Cu(NO3)2(aq).
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.
To balance the reaction Ni + C₄H₈N₂O₂ → Ni(C₄H₈N₂O₂)₂, the coefficients would be 1 for Ni and 2 for C₄H₈N₂O₂. This results in the balanced equation: 1 Ni + 2 C₄H₈N₂O₂ → 1 Ni(C₄H₈N₂O₂)₂.
NiCl2 + 2Na --> 2NaCl + Ni
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.
The color of Ni(NH3)6^2+ is violet.
Ammonia reacts with nickel sulfate to form nickel(II) hydroxide, which is a pale green precipitate. This reaction is a double displacement reaction where the ammonia displaces the sulfate ion to form the precipitate.
Nickel forms Hydrogen gas when reacts with dilute acid.
The reaction between nickel nitrate [Ni(NO3)2] and ammonia (NH3) can form a complex compound known as hexaamminenickel(II) nitrate, which has the formula Ni(NH3)62. This compound consists of a nickel ion coordinated with six ammonia molecules in an octahedral geometry.
This reaction is known as the double exchange reaction Ni(NO3)2(aq) + 2 NaOH(aq) --> Ni(OH)2(s) + 2 NaNO3(aq) (aq) means in aqueous solution (s) means solid, hence nickel hydroxide is seen precipitating out of the solution
