Calculate the concentration of the unknown propanoic acid


The Ka for propanoic acid is 1.34 * 10-5.  An unknown solution of propanoic acid (a weak monophonic acid) was pipetted (25.00 mL) into a flask and was titrated with 0.1012 MNaOH to a phenolphthalein endpoint.

a. Calculate the concentration of the unknown propanoic acid if it needed .56 mL of sodium hydroxide to reach the endpoint?

b. Calculate the pH of the solution after 8.78 mL of titrant (NaOH) was added?
