Textbook 6A.17

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

How do we tell when it's amphoteric or not?

most amphoteric oxides align with the metalloid diagonal. For example c and d are amphoteric because As and Bi are metalloids

Amphoteric simply means that the ion is able to act as both an acid and a base.

How would we know that SO3 is acidic? Couldn't it be amphoteric as well?
