Strong Bases

[Audra Mcleod 3G]

Hello!
I was kind of confused as to whether metal oxides were considered strong bases. I know that in lecture Lavelle said groups 1 and 2 hydroxides and oxides were strong, but the list of strong bases that Sapling provided only included groups 1 and 2 hydroxides (and said that any bases not in that list were weak). So I was wondering whether group 1/2 oxides were in fact considered weak, or is this just an incomplete list?

I have been looking on the web, and I cannot seem to find anywhere that lists group 1/2 metal oxides as strong bases. I would just go with what Sapling says because that is our main resource textbook

Hi!

So Table J.1 has a list of the common aqueous strong acids and bases that may hopefully help you understand!

Strong bases include group 1 hydroxides, alkaline earth metal hydroxides (Ca(OH)2, Sr(OH)2, and Ba(OH)2), and group 1 and group 2 oxides.

During today's step-up session, the UA said that Lithium, Sodium, Potassium, Calcium, Strontium, and Barium from groups 1 and 2 all form the strong bases. I think that's what you were asking about? Hope this helps! :)
