Consider the titration of 48.5 mL of 1.2 M NaOH with 1.0 M HCl. Find the pH at the following points.
a) At the start of the titration
b) At the equivalence point
c) After the addition of a large excess of the acid solution (in comparision with the acid volume needed to reach the equivalence point)
d) Tell how many milliliters of acid are required to reach the equivalence point.
