Temperature Range

The ionization constant of liquid D2O has been measured over the temperature range 298 to 523 K using an aqueous electrolyte concentration cell. Values for the standard free energy, enthalpy, entropy, and heat capacity of ionization have been calculated. The results are compared to similar results for liquid H2O
