For 10 points, name this process that often makes use of indicators such as phenolphthalein (FEE-nul-THAY-leen) and a buret.
The potentiometric form of this process involves measuring the potential difference between two cells and using the Nernst Equation. When this process is done using a polyprotic solution, there will be more than one equivalence point. At the half equivalence point of this process for a buffer solution, the pH equals the pKa, as shown by the Henderson-Hasselbalch Equation.
