State whether the following oxides are acidic, basic, or amphoteric:
a) BaO
b) SO3
c) As2O3
d) Bi2O3
Can someone walk me through this problem?
I know that amphoteric means it can act as both acid / base, but I'm confused on how to solve this question
Thank you!

Write out the likely reaction when the oxide is reacted with water. From there, determine whether the solution is acidic or basic.

As and Bi are metalloids and can act as either acids or bases.

And BaO is basic because if you look at the reaction of BaO + H2O = Ba(OH)2, it forms hydroxide compounds meaning it s gonna be a basic compound. The general rule of thumb is if metals typically form metal oxides.
