A benzoic acid solution was prepared by adding 0.488 g benzoicacid to a 100 mL volumetric flask and then adding enough water tobring the total solution volume to 100.00 mL. How many millilitersof 0.0989 M NaOH are required to titrate the entirebenzoic acid solution to the equivalence-point? What is the pH atthe equivalence-point?

If the experiment were repeated using the same mass of benzoicacid and a 50 mL volumetric flask instead of a 100 mL volumetricflask, how many milliliters of 0.0989 M NaOH would berequired to titrate the entire benzoic acid solution to theequivalence-point?
