1 Answer ; = ; 5.56 · = [OH−][HA][A−] = x20.1−x ≈ x20.1 x = (0.1Kb)12 = ; 7.46 · = [ ; ] pOH = -log( ; 7.46 · ) = 5.13 pH = 14 - pOH = 8.87.

pH depends on how much excess titrant has been added. Example: Strong acid – strong base titration. To reach equivalence point. HNO3 + KOH H2O(l) + KNO3(aq).
