### Ka, Kb, pKa, etc. on Final

Our TA mentioned that Ka and Kb won't be in the final, but we spent a considerable amount of time on it and it is in our outline. What do we really need to know about it besides its relationship to acidic/basic strengths?

I think that we'll go over Ka and Kb more in depth in 14B, but that we should know what they are conceptually for the final. So like, we won't be doing calculations right now but we might have to use the conceptual understandings to specify which acids/bases will be strong/weak. I hope this helps. :)

I think you should just know their relationships and that they are used primarily for weak acids and bases. For example, as one increases, the other decreases.
