WebAll data given in the figures apply to dilute aqueous solutions at ambient temperature. For amines, the pka value is given for the conjugate bases BH+ and BH22+. BH+ = B + H+. The pKb for a base may be calculated from the pKa value of its conjugate acid: pKw = pKa + pKb. At 25°C the pKw is 14 and. pKb = 14 - pKa.
