All acidic aqueous solutions contain protonated water, known commonly as the hydronium ion (H 3 O +). Brønsted acids release one or more of their protons (hydrogen ions), which combine with water ...

Acid catalysis by hydronium ions is ubiquitous in aqueous-phase organic reactions. Here we show that hydronium ion catalysis, exemplified by intramolecular dehydration of cyclohexanol, is markedly ...

The dehydration of alcohols is involved in many organic conversions but has to overcome high free-energy barriers in water. Here we demonstrate that hydronium ions confined in the nanopores of zeolite ...

Protons in aqueous solution can usually migrate very quickly -- much faster compared to other ions. However, this only applies when they are in a space greater than two nanometers, as a new study ...

Researchers have been able to directly visualize the neutral products of the mutual neutralization of hydronium and hydroxide, and report three different product channels: two channels were attributed ...

New computer calculations have revealed that a century-long assumption in chemistry is wrong. At the crux of the matter is the movement of the hydroxide ion, OH –, in water. Hydroxide ions and protons ...
