7th Edition Q6A #1

Postby Briana Perez 3A » Sun Dec 02, 2018 12:49 pm

Determine which are basic, acidic, or amphoteric..

a. BaO
b. SO3
c: As2O3
d: Bi2O3

For these problems, would it help to draw out the Lewis structures?
Or do you simply follow the rules stating that metals form basic oxides, nonmetals form acidic oxides, and the diagonal bar forms amphoteric?

Can someone please explain how they would go about solving this problem please!

A general trend is that metal oxides such as CaO are basic where as nonmetal oxides such as NO2 are acidic. Oxides are said to be amphoteric if they are attached to Metalloids such as B, As, Si, etc.
