Question M9

The question states, “Copper (II) nitrate reacts with sodium hydroxide to produce a precipitate of light blue copper (II) hydroxide. Write the net ionic equation for the reaction.” I’m not sure why the answer is Cu2+ + 2OH —> Cu(OH)2. Why is there no Na in the equation?

Net ionic equations only show the reactants that participate in the reaction. Since the reaction produces a copper hydroxide, the only reactants that matter are the copper and hydroxide. The sodium dissociates in the solution and does not contribute to the precipitate.
