Understanding Acid-Base Titration Curves and Endpoints

Quick fact

The steepest part of a titration curve occurs near the equivalence point, and a single drop of titrant can change the pH by several units—this is why indicator selection is so crucial.

Why this is interesting

You've probably seen a pH meter jump dramatically during a titration—but why does the pH stay almost constant for a while and then suddenly change? What's really happening inside the flask at that moment?
