The use of the initial vinegar and salt solution was to ensure the aluminum surface was clean and free from oxidesThis left elemental aluminum free to reactWhich ions reacted with aluminum metal? a.Ammonium, sodium, and calcium ions b.Lead (II), silver(I), and copper (II) ions c.Silver(I) and copper (II) ions d.Carbonate and hydroxide ions e.Sodium and calcium ions
Choice b is the best choice as aluminum is more active than these three metals, so it should donate electrons to the ions and convert them to metal atoms.
