Question details

Consider the titration of a weak base (B-) with a strong acid (HCl). Draw (this can be handdrawn) a pH (not pOH) vs mL HCl graph. If you start with a weak base, will the pH be low or high? As H+ is added, will the pHincrease or decrease?). Label the titration curve with letters A-E, and describe the relativequantities of the dissociated base (B-) and its conjugate acid (HB), H+ and OH- at each pointthroughout the titration (before the ½ equivalence point [A], at the ½ equivalence point [B],after the ½ equivalence point but before the equivalence point [C], at the equivalence point[D], and after the equivalence point [E]). Locate the position where pH = pKb on your graph.
