. In an acid-base titration, a standard solution of 1.0 MHCl is added to a solution of potassium hydroxide (KOH). As the standard solution is added to a beaker, how does the pH change near the equivalence point?
The pH increases very quickly, more quickly than earlier or later in the titration.

The pH decreases very quickly, more quickly than earlier or later in the titration.

The pH increases gradually, at the same rate as earlier and later in the titration.
