### pH calcuations

Are pH=-log(H+) and pH=-log(OH-) the only equations we need to know, regarding pH, for the final?

I believe so

Other than molarity calculations we did ad the beginning of the quarter, we have not done any other calculations with pH besides the ones you have mentions, so I assume so.

Regarding concentrations and the equations related to acid/base reactions I imagine we'll probably have to know those equations about Kb and Ka.

It may also be helpful to remember that pH + pOH = 14.

I think so, unless he gives us another one

That and pH+pOH=14, and perhaps equations relating to Ka.

### Re: pH calcuations

Just to clarify, I think it's a typo, but pH= -log(H+) and pOH= -log(OH-). Make sure the pH is associated with the H+ / H3O+ and the pOH is associated with the OH-
