Webband the pH increases • When the moles of base added equals half the total moles of acid, the weak acid and its conjugate base are in equal amounts. The ratio of CB / WA = 1 and according to the HH equation, pH = pKa + log(1) or pH = pKa. • If more base is added, the conjugate base form becomes WebbA base will give hydroxide ions in reaction with water. B (aq) + H2O (l) → HB+ (aq) + OH- (aq) From the pH we know pOH = 14 - 9.82 = 4.18. We can calculate now [OH-]. The [HB+] equals [OK-]. The actual concentration [B] = 0.1 - [HB+].
