Cations as Acids

Postby Bailey Giovanoli 1L » Fri Jan 15, 2021 9:36 pm

Does anyone know if the book shows the equilibrium constants of cations that are acids, like Al3+? I thought I saw it somewhere, but I can’t find it now.

I see those in table 6D. 1, so in the first table of the Solutions of Weak Acids section (6D). Does that help?

Yes, I think I figured it out. Thank you!!

what would be the best way to study for that topic?

I’d suggest just knowing which cations acid as acids. You won’t need to remember there Ka values. Those should be given in any question, and if they aren’t you’ll be able to solve for them. As a rule of thumb for cations that act as acids, you can find them in the table in the book. Al3+ is a common one used I’d recommend remembering.
