Dissociation chemistry of hydrogen halides in water [PDF]

open access: yesThe Journal of Chemical Physics, 2004
To understand the mechanism of aqueous acid dissociation, which plays a fundamental role in aqueous chemistry, the ionic dissociation of HX acids (X=F, Cl, Br, and I) in water clusters up to hexamer is examined using density functional theory and Møller–Plesset second-order perturbation methods (MP2).

Water Self‐Dissociation is Insensitive to Nanoscale Environments

open access: yesAngewandte Chemie, 2023
AbstractNanoconfinement effects on water dissociation and reactivity remain controversial, despite their importance to understand the aqueous chemistry at interfaces, pores, or aerosols. The pKw in confined environments has been assessed from experiments and simulations in a few specific cases, leading to dissimilar conclusions.
