@sweetburger It's B right?

I can't find the old question.

sweetburger · Answer

Is this the same question as the one before?

vera_ewing · Answer

Yep. I was looking for it, but I can't find it.

sweetburger · Answer

Alright what we look at is this Kw=(Ka)(Kb) if given Ka we solve for Kb like this Kw/Ka=Kb so considering we start initial with knowing the conjugate acid then it must initial be a base and bases have Kb dissociation values. So i think it is D.

I feel like the answer choices were different, maybe I just read them wrong last time.
