WebNov 5, 2024 · Kb's negative log base ten is equal to pKb, it works the same as pKa expect that it's for bases. {eq}pK_b = -logK_b {/eq} ... High values of Ka mean that the acid dissociates well and that it is a ... WebJul 7, 2024 · Thus titration methods can be used to determine both the concentration and the pKa (or the pKb) of a weak acid (or a weak base). ... Does high pKa mean strong acid? In addition, the smaller the pKa value, the stronger the acid. For example, the pKa value of lactic acid is about 3.8, so that means lactic acid is a stronger acid than acetic acid. ...

WebApr 14, 2016 · pKb = -log Kb A large Kb value indicates the high level of dissociation of a strong base. A lower pKb value indicates a stronger base. pKa and pKb are related by the simple relation: pKa + pKb = 14 What Is pI? Another important point is pI.

At what point do we consider it a strong base? I thought that the stronger the base, the bigger the Kb and the smaller the pKb. I would say that a pKb of 9,5 is pretty high, hence a weak base. and that is because Kb = [B+] [OH-] / [BOH. The stronger the base, the more it will dissociate, giving a bigger Kb, or ...
