Please help, I will give a huge thumbs up:)
An analytical chemist is titrating 105.9 mL of a 0.7000 M solution of butanoic acid (HC3H,CO2) with a 0.5200 M solution of KOH. The pKa of butanoic acid is 4.82. Calculate the pH of the acid solution after the chemist has added 118.1 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...
