WebAug 14, 2024 · We are given the pKa for butyric acid and asked to calculate the Kb and the pKb for its conjugate base, the butyrate ion. Because the pKa value cited is for a temperature of 25°C, we can use Equation 16.4.16: pKa + pKb = pK w = 14.00. Substituting the pKa and solving for the pKb, 4.83 + pKb = 14.00 pKb = 14.00 − 4.83 = 9.17 Webfind the pH of a buffer that consists of 0.27 M NH3 and 0.12 M NH4Cl. pKb of NH3=4.75.
