We first write down the balanced equation for this reaction:


This is a precipitation reaction, where two soluble salts are mixed together in solution forms to make a precipitate.

So, we can now write the ionic equation for this reaction, that is:


Now, we need to cancel the spectator ions, which are ions that are present on both sides in the equation. So, the equation becomes


The final net ionic equation is now:


The iron(II) hydroxide formed is easily oxidized when exposed to air and can easily become iron(III) hydroxide #(Fe(OH)_3)#.
