Consider the titration of a weak base (B- ) with a strong acid (HCl). Draw (this can be hand drawn) a pH (not pOH) vs mL HCl graph (it will not look the same as the one in question #13; if you start with a weak base, will the pH be low or high? As H+ is added, will the pH increase or decrease?). Label the titration curve with letters A-E, and describe the relative quantities of the dissociated base (B- ) and its conjugate acid (HB), H+ and OHat each point throughout 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.
