Thermometric Titration Curve

An acid-base reaction is exothermic, which means we can follow the titration by monitoring the titration mixture’s temperature as a function of the volume of titrant added. A typical thermometric titration curve is shown here. Prior to the equivalence point, the increase in temperature results from the reaction between the titrant and the tirand; after the equivalence point, the increase in temperature is due to the dissolution of the titrant—typically a strong acid or a strong base—in water.
