WebNov 26, 2015 · Could you elaborate a little this conclusion: Generally, acidic compounds (phenols, carboxylic acids, etc.) are more dissociated in D2O than H2O (ref). This would suggest that the equilibrium constant in eqn (I) would be larger than the equilibrium constant in eqn (II) – EJC. Nov 25, 2015 at 21:20.

The enthalpy of the isotope-exchange reaction: H2O + D2O
WebThe mass of deuterium, D, is 2.014 g/mol. Heavy water is water with the isotope deuterium in place of ordinary hydrogen, and its formula is D2O. The above reaction can be used … Web1 Background. “Heavy water” and “heavy hydrogen” were discovered by Harold C. Urey and co-workers in 1931. Heavy water is the oxide of deuterium, an isotope of hydrogen with one proton and one neutron in its nucleus. At the time of these discoveries, the neutron had not been discovered, thus the name “heavy hydrogen” was used for ... WebAug 6, 2015 · The adsorption of water and deuterium oxide on TiO 2 surfaces was investigated in the dark as well as under UV(A) irradiation using in situ ATR-FTIR spectroscopy under oxygen and oxygen free conditions.
