An analytical chemist is titrating of a solution of propionic acid with a solution of 224.9 ml of a 0.6100M solution of propionic acid (HC2H5CO2) with a 1.1000M solution of KOH. The pKa of proionic acid 4.89.
Calculate the pH of the acid solution after the chemist has added 41.04mL 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 solution added. Round your answer to decimal places.
