6A.17 (admin?)

How do we find c) and d) to be amphoteric? Is it just memorization? Also, the answer in the book saying those are amphoteric goes against what we learned in class.

The question is: "State whether the following oxides are acidic, basic or amphoteric: (a) BaO (b) SO3 (c) As2O3 (d) Bi2O3

I'm having trouble understanding the section in the textbook related to this question (6A3). Can someone walk me through how to begin approaching all of these, step-by-step? What are the criteria to assess and how do you apply them?
