An acid-base titration is a neutralization reaction that is performed in the lab in order to determine an unknown concentration of acid or base. The moles of acid will equal the moles of base at the equivalence point.
If three of the above quantities are known, the fourth can be calculated. In order to determine when a solution has been exactly neutralized, an acid-base indicator is used that changes color in a certain pH range (pH is a scale used to measure acidity). This color change is termed the endpoint of the titration.
