The question describes the reaction of copper(II) ions (Cu^2+) with sodium hydroxide (NaOH). This is a common precipitation reaction used to test for the presence of copper(II) ions. Step 1: Identify the reactants and their dissociation. The reactants are Cu^2+(aq) and NaOH(aq). Sodium hydroxide is a strong base and dissociates into Na^+(aq) and OH^-(aq) ions in water. Step 2: Determine the products of the reaction. Copper(II) ions (Cu^2+) react with hydroxide ions (OH^-) to form copper(II)
