WebpKb can be calculated by pKb = -log 10 (Kb). A large Kb value indicates the high level of dissociation of a strong base. A lower pKb value indicates a stronger base. Because these reactions occur in aqueous solutions, water is not included in the equation even though it is part of the reaction. WebIs high pKa more acidic? No higher pka means lower acidity. So the higher the pKa the smaller Ka, and this means a weaker acid. Higher pKa indicates weaker acid. What is the pKa of pure water at 25 ℃? The pKa value of pure water at 25 ℃ is …
