Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.

Question

An analytical chemist is titrating 117.3 mL of a 0.2700 M solution of butanoic acid (HC,H,Co,) with a 1.200 M solution
of KOH. The p K, of butanoic acid is 4.82. Calculate the pH of the acid solution after the chemist has added 14.63 mL of
the KOH solution to it.
Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of
KOH solution added.
