Title: Comment on “Accurate Experimental Values for the Free Energies of Hydration of H+, OH–, and H3O+”

Abstract

In the subject paper, Plascak and Shields claim to have derived accurate experimental values for the hydration free energies of H+, OH?, and H3O+. The purpose of this comment is to alert the community that, in fact, their values are less accurate than the values they are meant to replace. In what follows we show the errors PS made and, by example, give practical advice on how to ensure correct assignment of standard states for reactions with water as a reactant or product in gas and solution phases.

  • We have calculated the free energies of aqueous solvation of the hydrogen isotopes H, D, and Mu quantum mechanically, using path integral methods, to understand the effect of equilibrium solvation on the rate constant for the addition of hydrogen atom isotopes to benzene in aqueous solution. Within a classical mechanical model, the free energy of solvation of the hydrogenic solute is independent of its isotopic mass. However, when treated quantum mechanically, these solvation free energies can vary with solute isotopic mass. Our calculated Helmholtz free energies of solvation for the H and D isotopes are nearly the same, 2.53 [+-]more » 0.31 and 2.44 [+-] 0.29 kcal/mol, respectively, indicating that quantum effects on the solvation energetics are small for these systems. Similarly, our calculated Gibbs free energies of solvation for H and D are 3.23 [+-] 0.32 and 3.29 [+-] 0.35, respectively. The calculated free energy of solvation of H is in qualitative agreement with the experimental estimate. We have also calculated the Helmholtz and Gibbs free energies of solvation at 300 K for the light hydrogenic isotope muonium (Mu). 24 refs., 4 figs., 4 tabs.« less
  • The diffusion Monte Carlo (DMC) method is applied to compute the ground state energies of the water monomer and dimer and their D{sub 2}O isotopomers using MB-pol; the most recent and most accurate ab inito-based potential energy surface (PES). MB-pol has already demonstrated excellent agreement with high level electronic structure data, as well as agreement with some experimental, spectroscopic, and thermodynamic data. Here, the DMC binding energies of (H{sub 2}O){sub 2} and (D{sub 2}O){sub 2} agree with the corresponding values obtained from velocity map imaging within, respectively, 0.01 and 0.02 kcal/mol. This work adds two more valuable data points thatmore » highlight the accuracy of the MB-pol PES.« less
  • High precision measurements of the vapor pressure differences between some deuterated benzenes B-d/sub x/ (x=1, para-2, and 6) and protio benzene B-d/sub 0/; between para- and ortho-, and para- and meta-dideuterobenzene; and between perdeuterocyclohexane C-d/sub 12/ and protiocyclohexane C-d/sub 0/ were made from near the freezing point to the normal boiling point. The data are best represented as the logarithmic ratios ln R (d/sub 6/) =ln (P/sub d/0/P/sub d/6) =1226.5/T/sup 2/-12.178/T, ln R (para/ortho) =ln (P/sub parahyphend/2/P/sub orthohyphend/2) =2.6/T/sup 2/, and ln R (para/meta) =ln (P/sub parahyphend/2/P/sub metahyphend/2) =-2.0/T/sup 2/, together with the deviations from the law of the meanmore » ..delta.. (d1) =6-(ln R (d/sub 6/)/lnR (d/sub 1/))=0.177-3.6 x 10/sup -4/t and ..delta.. (d/sub 2hyphenpara/=3-(ln R (d/sub 6/)/ln R (d/sub 2hyphenpara/))=0.028 +1.0 x 10/sup -4/t. The isotope effects are inverse and display significant deviations from the law of the mean. The cyclohexane results are given by ln R (C-d/sub 12/) =-2188.4/T/sup 2/-18.587/T. New measurements of the vapor pressures of benzene--cyclohexane solutions are also reported between 5 and 80 /sup 0/C. The data are in good agreement with the best earlier work. Excess free energies of the equimolar solutions B-h/sub 6//B-d/sub 6/ and C-h/sub 12//C-d/sub 12/ have been measured between 20 and 80 /sup 0/C. Suitable fits to the data yield the following results (30 /sup 0/C); G/sup ex/(B-h/B-d), G/sup ex/(C-h/C-d); H/sup ex/(B-h/B-d),« less
  • In a recent letter by Sawyer, it was suggested that new values of the bond dissociation energies (BDE), defined for bond-breaking processes in the gas phase at 298 K, for a number of hydrogen- and oxygen-containing species could be determined from half-cell potentials. Discrepancies with accepted values for HO{sub 2} and HO{sub 2}{sup {minus}} were noted. We wish to point out that the bond dissociation energies for H-OO and H-OO{sup {minus}} that were derived by Sawyer are in serious disagreement with those established in the past decade by gas-phase chemical kinetics and photoelectron spectroscopy. These results were not cited bymore » Sawyer. Moreover, computations utilizing half-cell potentials for the derivation of bond dissociation energies must account for substantial solvation effects. When properly calculated, these BDEs are, in fact, in accord with established values.« less
