Consider the following three titrations: 100.0 mL of 0.100 M HCl titrated with 0.100 M NaOH 100.0 mL of 0.100 M NH3 (Kb = 1.8x10-5) titrated with 0.100 M HCl 100.0 mL of 0.100 M HF (Ka = 3.5x10-4) titrated with 0.100 M NaOH Which of the titrations will have the highest pH at the halfway point? a.1 b.2 c.3 d.They all have the same pH at the halfway point.
