    A weak acid, HA, is partially titrated using NaOH. You start with 50.0mL of a 0.100 M HA and add 30.0 mL of a 0.100 M NaOH, and measure the pH of the solution at 7.00. What is the pKA of Ha? What would be the pH of the titration at the equivalence point (when 50.0 mL of NaOH is added)? I got the correct answer for the pKa (6.82), but don't know how to approach the second part. The...
