# What is the net ionic equation for the reaction of copper(II) ion with iron?

$1 C {u}^{+ 2} + 1 S {O}_{4}^{-} 2 + 1 F {e}^{0} \to 1 F {e}^{+ 2} + 1 S {O}_{4}^{-} 2 + 1 C {u}^{0}$ ionic equation.
$1 C {u}^{+ 2} + 1 F {e}^{0} \to 1 C {u}^{0} + 1 F {e}^{+ 2}$ net ionic equation.
The water ${H}_{2} O$ does not ionize or change, so it is not part of either the ionic equation or the net ionic equation.
The sulfate ion $S {O}_{4}^{-} 2$ does not change so, while it part of the ionic equation, it is not part of the net ionic equation.
