analyze and conclude

1. which of the ions used in the experiment were cations?
2. which of the ions used in the experiment were anions?
3. which of the ions used in the experiment were polyatomics?

Explanation:

1. Cations are positively - charged ions. In the experiment, \(Fe^{3+}\), \(Ag^{+}\), and \(Pb^{2+}\) are cations as they have positive charges.
2. Anions are negatively - charged ions. Here, \((CO_{3})^{2 -}\), \((OH)^{-}\), and \((PO_{4})^{3 -}\) are anions due to their negative charges.
3. Polyatomic ions are ions composed of more than one atom. \((CO_{3})^{2 -}\), \((OH)^{-}\), and \((PO_{4})^{3 -}\) are polyatomic ions as they consist of multiple atoms.

Answer:

1. \(Fe^{3+}\), \(Ag^{+}\), \(Pb^{2+}\)
2. \((CO_{3})^{2 -}\), \((OH)^{-}\), \((PO_{4})^{3 -}\)
3. \((CO_{3})^{2 -}\), \((OH)^{-}\), \((PO_{4})^{3 -}\)
