Binary ionic compounds typically consist of a metal and a nonmetal. In each of these compounds, the metal forms only one type of ion. Ionic bonds are electrostatic forces of attraction, that is, the attractive forces experienced between objects of opposite electrical charge (in this case, cations and anions). We know that cobalt can have more than one possible charge; we just need to determine what it is. It is also known as filter alum or dialuminium trisulphate. Because the total number of positive charges in each compound must equal the total number of negative charges, the positive ions must be Fe3+, Cu2+, Ga3+, Cr4+, and Ti3+.
