Thermometric titrimetry gives the analyst another dimension in analytical problem solving, since it employs the most basic property of chemical reactions - enthalpy change - to detect the endpoint
Thermometric titrimetry offers the analyst speed, accuracy and precision.
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 (deltaH).
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.
Scope of thermometric titration.
Thermometric titration is a very versatile determination method and an ideal complement to potentiometric titration.
In principle it is suitable for any reaction that produces a sufficiently large temperature change in the sample solution.
It is particularly suitable for applications for which no suitable potentiometric sensor is available, for which no suitable reference electrode is available, in which the sample affects the indicator electrode or destroys it, for which no solvent is available that is suitable for potentiometry.
Now available: Practical thermometric titration monograph free of charge.
Enthalpy change is a universal property of chemical reactions.
This monograph gives you an introduction into the theoretical aspects of thermometric titrimetry, some practical considerations about its benefits and limitations and provides you an overview of the applications that can be solved with thermometric titration.
