WebFeb 8, 2013 · pKa > 14 just means it's a really weak acid or very strong base. In an acid dissociation reaction, you'll see a large pKa if the Ka is small (pKa = -log (Ka) ), which means that the acid doesn't dissociate well. It would probably need a very strong base to dissociate but generally, it just means a very weak acid. 0 milski 1K member 5+ Year Member WebApr 28, 2024 · Definition of pKb: pKb = − log10Kb Kb = 10 − pKb Relationship between pKa and pKb of a conjugate acid–base pair: pKa + pKb = pKw pKa + pKb = 14.00at 25°C …
