Answer
Net Ionic: $Fe^{+2}(aq)$ + $2OH^{-}(aq)$ $\rightarrow$ $Fe(OH)_{2}(s)$
Spectator Ions: $K^{+}$ and $NO_{3}^{-}$
Work Step by Step
When iron reacts with hydroxide, it forms a solid so this will be included in the net ionic. Potassium nitrate is soluble so it will not be included in the net ionic equation and is known as spectator ions.
