A calorimetry study of hematite surface reactions is reported, with special emphasis on the estimation of the electrostatic contribution to the enthalpy of charging. The calorimetry titrations were performed outside the point of zero charge region where the electrostatic contribution is significant. The results were interpreted by the surface complexation model. The interpretation enabled the evaluation of standard protonation and deprotonation enthalpies as well as the electrostatic contribution to these quantities.

simple model is developed to describe wave phenomena at electrode/electrolyte interfaces. The electrochemical kinetics include a negative faradaic impedance in order to provide the necessary feedback between the interfacial faradaic current and the local currents flowing in the electrolyte solution.
