What is a thermometric titration?

Titration is the oldest and most widespread method used in analytical chemistry. For a long time now, potentiometric sensors (indicator electrodes) have been used to cover a wide range of applications in the titration field. As a result, potentiometric titration has become an established analytical method and features in many standards.

The electrochemical potential is only one of the possible ways of following a chemical reaction. A far more universal parameter is the reaction enthalpy.

Every chemical reaction is accompanied by a change in enthalpy (ΔH). As long as the reaction takes place, this results in either an increase (exothermal reaction) or decrease (endothermal reaction) in the temperature of the sample solution. For a simple reaction this means that the increase or reduction in temperature depends on the converted amount of substance.
