WebThe pKa of butanoic acid is 4.82 . Calculate the pH of the acid solution after the chemist has added 20.8mL of the KOH solution to it. Question: An analytical chemist is titrating 55.8mL of a 0.9700M solution of butanoic acid (HC3H7CO2) with a solution of 0.8200M KOH . The pKa of butanoic acid is 4.82 . WebThe concentration of an acid solution can be determined by titration with a strong base. First, calculate the number of moles of strong base required to reach the equivalence point of the titration. Then, using the mole ratio from the balanced neutralization equation, convert from moles of strong base to moles of acid.
