K constant and pK value

[gabbymaraziti]

Do we need to know how to calculate the Ka, acid dissociation constant, and Kb, the base dissociation constant? Or are these the same as the K constant itself?

Also, is Kw within our scope?

[Andrew Liang 1I]

I don't think we will be asked to find the Ka and Kb because they are for weak acid and weak bases. I don't think we will be asked to find those until 14B. I'm not too sure though. Kw was never in the lecture slides, so I doubt that it will be in the exam

I'm pretty sure we aren't going to do actual calculations with Ka until 14B. What does Kw represent, though? I don't remember learning that

Kw represents the constant for H20. Kw=[H+][OH-]=1.0x10^-14
