Synonym: enthalpimetric titration
An analytical method in which one reactant (the @[email protected]) is added continuously or stepwise to an @[email protected] or isoperibol vessel containing another reactant. The @[email protected] change(s) of the ensuing reaction(s) causes a temperature change which, when plotted versus volume of @[email protected], may be used to find the @[email protected] endpoint(s). This is the preferred term for experiments producing plots of temperature versus volume of @[email protected] in which the main goal is a quantitative determination. Nonetheless, when a calorimetric vessel is used, such that the @[email protected] is known, thermodynamic parameters may also be estimated from such experiments. An acceptable synonym in that case is enthalpimetric titration. The use of the adjective @[email protected] is justified because of widespread historical and current usage, and because a @[email protected] of necessity implies a chemical reaction. The term @[email protected] has been used, but is not recommended. A method in which the @[email protected] is a @[email protected] for an @[email protected] that occurs after the endpoint for the analyte reaction should be called a @[email protected] @[email protected] with catalytic endpoint detection, not a @[email protected]
