Determining acidic vs basic

[Heather Szeszulski 1I]

BaO is this basic because it is a non metal with O
SO3 and is this acidic because it is a metal with O
Or is there another way do distinguish the two?

[Ethan Laureano 3H]

To memorize acids you'll just have to memorize (typically they'll have H in the front, but not always). The strong acids are HCl, HBr, HI, H₂SO₄, HNO₃, HClO₃, and HClO₄. For bases, it's a bit easier. Strong bases are group 1 and 2 hydroxides (OH) and oxides (O).

I am confused because it says BaO is acidic??

[Isaac Wen]

I'm pretty sure BaO is a strong base. Can I ask where you saw that it was an acid?

[Justin Nguyen 3E]

Yeah, BaO should definitely be one of the strong bases because it can react with H2O to produce Ba(OH)2.

Hi just to clear up the confusion and for the final, Professor Lavelle said we should know the list of strong acids and bases. If it is not on the list then we can assume it is a weak acid or base.
