Consider the titration of 50.0 mL of 1.2 M NaOH with 1.0 M HCl. Find the pH at the following points.
At the start of the titration
At the equivalence point
After the addition of a large excess of the acid solution (in comparison with the acid volume needed to reach the equivalence point).
Tell how many milliliters of acid are required to reach the equivalence point.
