7.12: Relationship between Ka, Kb, pKa, and pKb

WebFor example if pKa = 4, then pKb = 10, and if pH = 11, then pH > pKb > pKa. I think you're thinking of pOH > pKb, in which case pH would indeed be < pKa (if pOH = 11, then pH = 3 < 4). Only time this wouldn't apply is when pKb > pKa, which I'm not 100% sure ever happens so I'm gonna ask in another post lol.
