An analytical method in which one reactant (the @T06386@) is added continuously or stepwise to an @A00141@ or isoperibol vessel containing another reactant. The @E02141@ change(s) of the ensuing reaction(s) causes a temperature change which, when plotted versus volume of @T06386@, may be used to find the @T06387@ endpoint(s). This is the preferred term for experiments producing plots of temperature versus volume of @T06386@ in which the main goal is a quantitative determination. Nonetheless, when a calorimetric vessel is used, such that the @H02753@ 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 @T06329@ is justified because of widespread historical and current usage, and because a @T06387@ of necessity implies a chemical reaction. The term @T06330@ has been used, but is not recommended. A method in which the @T06386@ is a @C00876@ for an @C01380@ that occurs after the endpoint for the analyte reaction should be called a @T06329@ @T06387@ with catalytic endpoint detection, not a @C00900@.
