Dissociation chemistry of hydrogen halides in water [PDF]
The 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).

Effects of Dissociation Water Retention on Pore Structure Disintegration in Hydrate Sediments
Frontiers in Energy Research, 2020 During the depressurization process, natural gas hydrates (NGHs) decompose and release methane gas and water. Field experience shows that only 1% of the dissociation water is recovered, hindering the continuous pressure decline and further NGHs ...

Water Self‐Dissociation is Insensitive to Nanoscale Environments
Angewandte 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.

Gas hydrate growth and dissociation in narrow pore networks: capillary inhibition and hysteresis phenomena [PDF]
, 2009 Marine sediments hosting gas hydrates are commonly fine-grained (silts, muds, clays) with very narrow mean pore diameters (0.1 mm). This has led to speculation that capillary phenomena could play an important role in controlling hydrate distribution in
