Write the complete equation and the net ionic equation for the following:
{eq}\rm Zn (s) + Cu(NO_3)_2 \to {/eq}
Question:
Write the complete equation and the net ionic equation for the following:
{eq}\rm Zn (s) + Cu(NO_3)_2 \to {/eq}
Net Ionic Equation:
In a net ionic equation, all of the spectator ions are omitted. These ions remain as ions in solution in do not participate in the formation of the desired product. This means that all the species written in a net ionic equation are all directly involved in the desired reaction.
Answer and Explanation: 1
According to the reactivity series, Cu is less reactive than Zn. This means that {eq}\rm{Cu^{2+} }{/eq} can be reduced by Zn to Cu. This results in the oxidation of Zn to {eq}\rm{Zn^{2+} }{/eq}.This is the redox reaction that occurs when Zn displaces {eq}\rm{Cu^{2+} }{/eq} in {eq}\rm{Cu(NO_3)_2 }{/eq}. The net ionic equation for this reaction is shown below.
$$\rm{Zn\left(s\right)+Cu^{2+}\left(aq\right)\to Zn^{2+}\left(aq\right)+Cu\left(s\right) }$$
