On the theory of thermometric titration

Enthalpimetric analysis

“…where Q denotes the total amount of heat evolved (or absorbed), np the number of moles of product formed, and AH the molar enthalpy of reaction. Furthermore, the temperature change, AT, observed in an adiabatic cell can be explicated as in Equation 2: AT = Q/K (2) where K denotes the effective heat capacity of the system. Combination of Equations 1 and 2 yields AT = -A.H-np K…”

“…In a recent communication (2), it has been suggested that the hitherto universally accepted linear relationship between AT and the volume of added titrant, Av, is valid only over a narrow range of volume if one takes into account that some heat transfer actually occurs between the ambient medium and the reaction cell which is necessarily not quite 100% adiabatic.…”

It is recommended that a more practical representation of a thermometric enthalpy titration would be achieved by a plot of 1/ vs. 1/ .…”
