what is the net ionic equation for:
Mn+Ni(NO3)2 -> Mn(NO3)2+Ni
Is the answer no reaction or is Nickel considered a state change??
In this reaction, both Mn and Ni(NO3)2 are solid, as well as the products Mn(NO3)2 and Ni. Given that all elements are in their solid state, there is no net ionic equation for this reaction.
However, it's important to note that this reaction is unlikely to occur as the reactants are stable, and there is no driving force (such as a reduction in charge) for the reaction to proceed. In reality, there would be no reaction.
To determine the net ionic equation for the reaction between Mn+Ni(NO3)2, first we need to write the complete ionic equation.
The chemical equation is:
Mn + Ni(NO3)2 -> Mn(NO3)2 + Ni
We can break down the soluble compounds into their ions:
Mn + Ni^2+ + 2NO3- -> Mn^2+ + 2NO3- + Ni
Next, we cancel out the spectator ions, which are the ions that appear on both sides of the equation and do not participate in the reaction. In this case, the NO3- ions are present on both sides and hence they are spectator ions.
Therefore, the net ionic equation is:
Mn + Ni^2+ -> Mn^2+ + Ni
So, the reaction does involve a change in the oxidation state of Nickel (Ni), and the net ionic equation correctly represents the relevant species involved.
To determine the net ionic equation for a given chemical reaction, we need to first examine the state of the reactants and products involved.
In this case, the reactants are Mn(NO3)2 and Ni, while the products are Mn(NO3)2 and Ni. The nitrate (NO3-) ions are common on both sides of the reaction, so they will not be included in the net ionic equation.
Let's break down the reaction and identify the dissociated ions:
Reactants:
Mn(NO3)2 -> Mn2+ + 2 NO3-
Ni -> Ni
Products:
Mn(NO3)2 -> Mn2+ + 2 NO3-
Ni -> Ni
As you mentioned, the nickel (Ni) does not undergo a state change. It remains in its elemental form on both sides of the reaction.
Now, if we cancel out the unchanged ions that appear on both sides, we get the net ionic equation:
Net Ionic Equation: Mn2+(aq) + Ni(s) -> Mn2+(aq) + Ni(s)
In this case, there is no net change or reaction observed. The net ionic equation confirms that the nickel (Ni) is not participating in any chemical change and remains the same element throughout the reaction.
