Questions: Write the balanced COMPLETE ionic equation for the reaction when Fe(NO3)3 and NaOH are mixed in aqueous solution. If no reaction occurs, simply write only NR. Be sure to include the proper phases for all species within the reaction.
Transcript text: Write the balanced COMPLETE ionic equation for the reaction when $\mathrm{Fe}\left(\mathrm{NO}_{3}\right)_{3}$ and NaOH are mixed in aqueous solution. If no reaction occurs, simply write only NR. Be sure to include the proper phases for all species within the reaction.
Solution
Solution Steps
Step 1: Identify the Reactants and Products
The reactants in this reaction are iron(III) nitrate, \(\mathrm{Fe(NO_3)_3}\), and sodium hydroxide, \(\mathrm{NaOH}\). When these two compounds are mixed in aqueous solution, a double displacement reaction occurs, forming iron(III) hydroxide, \(\mathrm{Fe(OH)_3}\), and sodium nitrate, \(\mathrm{NaNO_3}\).
Step 2: Write the Molecular Equation
The molecular equation for the reaction is:
\[
\mathrm{Fe(NO_3)_3(aq) + 3NaOH(aq) \rightarrow Fe(OH)_3(s) + 3NaNO_3(aq)}
\]
Step 3: Write the Complete Ionic Equation
In the complete ionic equation, all strong electrolytes (soluble ionic compounds) are dissociated into their ions:
\[
\mathrm{Fe^{3+}(aq) + 3NO_3^-(aq) + 3Na^+(aq) + 3OH^-(aq) \rightarrow Fe(OH)_3(s) + 3Na^+(aq) + 3NO_3^-(aq)}
\]
Step 4: Cancel Spectator Ions
Spectator ions are ions that appear on both sides of the equation and do not participate in the reaction. In this case, the spectator ions are \(\mathrm{Na^+}\) and \(\mathrm{NO_3^-}\).
Step 5: Write the Net Ionic Equation
After removing the spectator ions, the net ionic equation is:
\[
\mathrm{Fe^{3+}(aq) + 3OH^-(aq) \rightarrow Fe(OH)_3(s)}
\]
Final Answer
The balanced complete ionic equation for the reaction is:
\[
\boxed{\mathrm{Fe^{3+}(aq) + 3OH^-(aq) \rightarrow Fe(OH)_3(s)}}
\]
