Your lab partner produces a 250 mL solution by adding 45 mL of 1.85 M KOH to a solution of   0.58 M chloroacetic acid. What is the pH of the original solution A?

An analytical chemist is titrating 149.7 mL of a 0.5500M solution of benzoic acid (HC H CO,) with a 0.8000 M solution of NaOH. The p K of benzoic acid is 4.20. Calculate the pH of the acid solution after the chemist has added 16.29 mL of the NaOH solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of NaOH solution added.
