A new study provides fresh insight into traditional acid-base chemistry by revealing that the mutual neutralization of isolated hydronium (H₃O⁺) and hydroxide (OH⁻) ions is driven by electron transfer ...

A joint X-ray/neutron diffraction study has enabled the direct observation of a hydronium ion coordinated by three amino-acid residues of an enzyme. This sighting will affect our views on how enzymes ...

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 ...
