Titration is a method of chemical analysis in which a reactive substance is slowly added to anothersubstance, and some property of the combined substance is measured.

Suppose we have a formula for the titration function P(x). What calculation would we want to do to find the equivalence point? What is our mathematical name for that type of point?

Titration is a method of chemical analysis in which a reactive substance is slowly added to another
substance, and some property of the combined substance is measured. This procedure is taught in
CHM 116, General Chemistry II.
We will be looking at an example of acid-base titration. Specifically, 25 mL of an unknown
monoprotic weak acid is titrated against 0.105M NaOH (which is a strong base). This means we
are adding the base to the acid using a burette in a slow and precisely controlled manner. We
measure the pH after each addition. (A pH of less than 7 is an acid, and a pH of more than 7 is a
base.)
