State whether the following oxides are acidic, basic, or amphoteric: (a) BaO; (b) SO3; (c) As2O3; (d) Bi2O3.

Would the only approach to this be drawing the Lewis structures? Thanks!

Basically, metal oxides react with water to form strong bases. Many nonmetal oxides react after to form acids. Amphoteric compounds are found between the metal oxides and the nonmetal oxides of the period table along the diagonal band of the metalloids. These amphoteric compounds will include Be, Al, Ge, Sn, Sb, and Pb.

For these types of questions, typically the periodic table and an element's metallic or nonmetallic properties are used to determine whether or not something is acidic, basic, or amphoteric.
