Abstract

The limiting molar conductances Λ0 of potassium deuteroxide KOD in D2O and potassium hydroxide KOH in H2O were determined at 25°C as a function of pressure to disclose the difference in the proton-jump mechanism between an OH (OD) and a H3O+ (D3O+) ion. The excess conductance of the OD ion in D2O λ OE (OD -), as estimated by the equation

$$\lambda _E^O (OD^ - ) = \Lambda ^O (KOD/D_2 O) - \Lambda ^O (KCl/D_2 O)$$

increases a little with pressure as well as the excess conductance of the OH ion in H2O

$$\lambda _E^O (OH^ - ) = \Lambda ^O (KOH/H_2 O) - \Lambda ^O (KCl/H_2 O)$$

However, their rates of increase with pressure are much smaller than those of the excess deuteron and proton conductances, λ OE (D +) and λ OE (H +). With respect to the isotope effect on the excess conductance, λ OE (OH -)/λ OE (D +) decreases with presure as in the case of λ OE (H +)/λ OE (D +), but the value of λ OE (OH -)/λ OE (OD -) itself is much larger than that of λ OE (H +)/λ OE (D +) at each pressure. These results are ascribed to the difference in the pre-rotation of water molecules, which is brought about by the difference in the intial orientation of the rotating water molecule adjacent to the OH (OD) or the H3O+ (D3O+) ion.
