We have made calorimetric measurements of the enthalpies of reaction of I2O5(c) with water and with a small excess of OH−(aq) and have combined the results to obtain ΔH0 = 13.340 kcal mol−1 for the standard enthalpy of ionization of water. It is suggested that this approach can be applied usefully to investigation of the enthalpy of ionization of D2O for which there are still unresolved differences between reported values.

We have made glass electrode measurements that lead to values for the equilibrium constant for acid ionization of nitroethane in water and in aqueous ethanol mixed solvent systems. Calorimetric measurements have led to ΔH0 values for the acid ionization of nitroethane in water and in aqueous ethanol. These results have been combined to yield TΔS0 values for the ionization reactions in water and in aqueous ethanol. Our results have also been combined with previously reported equilibrium constants for ionization of water in aqueous ethanol to obtain thermodynamic data for the neutralization of nitroethane in the various solvent systems.
