Solution: Consider the following titrations.      I.   100 mL of 0.100 M acetic acid titrated with 0.100 M NaOH      II.  100 mL of 0.100 M acetic acid titrated with 1.00 M NaOH      III. 100 mL of 0.100 M hydrofluoric acid (HF) titrated with 0.100 M NaOH      IV. 100 mL of 0.100 M HCl titrated with 0.100 M NaOH      Which of these titrations produces the most basic solution at the equivalence point?                      A. I                      B. II                      C. III                      D. IV                      E. I and II are the same (and most basic)
