2. Placing aluminum foil in any solution containing aqueous copper(II) ions will result in a reaction. The reaction is slow to begin with, but then proceeds rapidly.
(a) Referring to the solubility table, name at least four ionic compounds that could be dissolved in water to make a solution containing aqueous copper(II) ions.
(b) Write a balanced chemical equation for the reaction of aluminum with one of the compounds you suggested in (a).
(c) Write the total ionic equation for the reaction.
(d) Write the net ionic equation for the reaction.
